Auditioning tools for a media editing application

ABSTRACT

Some embodiments provide a media editing application. The application places several committed media clips in a composite display area to specify a description of a composite presentation. In response to receiving a request to create a new version for a first media clip placed at a particular location in the composite display area, the application creates an audition set at the particular location in the composite display area. The application creates a second media clip from the first media clip. The application adds the first and second media clips to the audition set. At least one of the first and second media clips is a candidate media clip that is insertable at the location in the composite display area but is not a media clip that has been committed for inclusion in the description of the composite presentation.

BACKGROUND

Digital graphic design, image editing, audio editing, and video editingapplications (hereafter collectively referred to as media contentediting applications or media editing applications) provide graphicaldesigners, media artists, and other users with the necessary tools tocreate a variety of media content. Examples of such applications includeFinal Cut Pro® and iMovie®, both sold by Apple, Inc. These applicationsgive users the ability to edit, combine, transition, overlay, and piecetogether different media content in a variety of manners to create aresulting media project. The resulting media project specifies aparticular sequenced composition of any number of text, audio, image,and/or video content elements that is used to create a mediapresentation.

Various media editing applications facilitate such composition throughelectronic means. Specifically, a computer or other electronic devicewith a processor and computer readable storage medium executes the mediaediting application. In doing so, the computer generates a graphicalinterface whereby designers digitally manipulate graphicalrepresentations of the media content to produce a desired result.

One difficulty in media editing is that a user cannot convenientlyevaluate different types of media clips (e.g., a video clip, an audioclip, a sequence of media clips, an image, etc.) for a particularsection of a presentation. For example, in some instances, a user maywish to evaluate a particular section of the presentation using a videoclip with its accompanying sound (e.g., an audio and video clip), thevideo clip without its accompanying sound (e.g., a video clip), thevideo clip with an effect applied to it (e.g., sound effects or videoeffects), the video clip with different in and out points, etc.Moreover, a user may wish to evaluate different sequences of mediaclips, different scene durations (e.g., a single media clip versus asequence of media clips), etc.

Typically, if a user wishes to evaluate different types of media clipsthan those included in the composite presentation, the user must selectfrom a large group of media clips by iteratively accessing variousdifferent types of media clips. Thus, there is a need for a flexiblemedia editing application that allows a user to associate differenttypes of media clips with various sections of a composite presentation.

BRIEF SUMMARY

For a media editing application that creates composite presentations,some embodiments of the invention provide a novel auditioning tool thatallows a user to examine and maintain several different media clips thatare candidates (also referred to as “candidate media clips”) foraddition at or near a particular location in a composite display areaand to select one of the media clips to be included in the compositepresentation.

A media clip in some embodiments is a piece of media content. Examplesof types of media content include audio data, video data, audio andvideo data, text data, image/picture data, and/or other media data. Insome embodiments, a media clip can be a video clip or an audio clip. Inother embodiments, a media clip can be a video clip, an audio clip, anaudio and video clip, a sequence of media clips (also referred to as acomposed media clip or a media clip sequence), a text clip, a textoverlay, a still image or picture, or any other type of media clip thatcan be used to create a composite presentation.

For some embodiments of the invention, a graphical user interface(“GUI”) of a media editing application with an auditioning tool thatenables the user to create an audition set that includes several mediaclips. Typically, an audition set, in some embodiments, includes two ormore media clips that are specified as candidates that can be added at aparticular location in a composite display area to specify a descriptionof a composite media presentation. In some of these embodiments, all themedia clips in an audition are considered candidate media clips(including the “active pick,” described below). In other embodiments, anaudition set includes one or more media clips that are specified ascandidates that can be added at a particular location in the compositedisplay area. For some of these embodiments, the active pick of anaudition is not a candidate media clip. In addition, as described below,an audition set of some embodiments can include one media clip.

Some embodiments of a media editing application include a media librarythrough which the application's user can select media clips to add to apresentation that the user is compositing with the media editingapplication and a composite display area that provides a visualrepresentation of the composite presentation being created by the user.Media clips that are part of the composite presentation are referred tobelow as “committed media clips.” The media editing application of someembodiments allows media clips to be added to the composite display areaas candidate media clips. In some embodiments, candidate media clips aremedia clips that are candidates for adding to the composite presentationas they have not yet been added to the composite presentation.

In some embodiments, the composite display area specifies a descriptionof a composite presentation (also referred to as a “composite mediapresentation” or a “composite representation”). The composite displayarea of some embodiments includes a central compositing lane that spansa timeline and displays a graphical representation of the compositepresentation by displaying media clips that form the compositepresentation. One or more media clips can be placed on the centralcompositing lane. In some embodiments, no two committed media clips canoverlap on the central compositing lane.

Furthermore, media clips can be placed (“anchored”) off of media clipsplaced in the central compositing lane in regions above and below (notshown) the central compositing lane. Media clips placed in such regionsare referred to as “anchored media clips.” In some embodiments, severalhorizontal areas that span the timeline form quasi-tracks that are alsoreferred to as “anchor lanes.” In some of these embodiments, media clipscan be placed in these anchor lanes to anchor off of media clips in thecentral compositing lane. Instead of, or in conjunction with, havingseveral levels of media clips that anchor off the central compositinglane, some embodiments allow media clips to be placed in these anchorlands and to be anchored off of other anchored media clips placed inthese anchor lanes.

Media clips may be displayed with different appearances in differentareas of the GUI. For instance, the media clips in the media library canbe represented using a thumbnail view (i.e., media clips are representedusing a set equally-sized images) while the media clips in the compositedisplay area can be represented using a timeline view (i.e., media clipsare represented using a set of rectangular representations where thehorizontal length of the rectangle provides a visual indicator of thelength or duration of the associated media clip).

In some embodiments, one of the media clips in an audition set isselected as the “active pick” of the audition set. An active pick is amedia clip in an audition set that is specified to interact with themedia editing application. As such, the characteristics and attributes(e.g., graphical representation, effects, associated keywords, markers,etc.) of the active pick are used when the audition set interacts withthe media editing application. For instance, when an audition set isplaced at a particular location in the composite display area, theactive pick is the media clip that is committed at the particularlocation in the composite display area. Similarly, the graphicalrepresentation of the active pick is used as the graphicalrepresentation of the audition set (e.g., a thumbnail view in the medialibrary or a media clip view in the composite display area) in some ofthese embodiments. As another example, the media content of the activepick is displayed when a playback or skim operation is performed on theaudition set. In yet another example, the keywords associated with theactive pick are used to determine whether the audition set should bereturned as part of a result of a keyword search performed on mediaclips. In some embodiments, when an edit operation is performed on theaudition set, the operation is performed on only the active pick. Insome embodiments, however, some or all of the edit operations that canbe performed on the audition set are performed on all of the media clipsin the audition set.

Different embodiments provide different methods for selecting an activepick when an audition set is initially created. For example, someembodiments select a random media clip in the audition set as the activepick. Other embodiments select a media clip in the audition set based onsome criteria, such as media clip duration, media clip creation time,order of media clip selection (e.g., first selected, last selected) whencreating the audition set, location of media clips (e.g., set the mediaclip in the composite display area as the active pick), etc. Othermethods for determining which media clip to select as the active pickare possible.

In some embodiments, a user selectable user interface (“UI”) item isdisplayed on an audition set displayed in the composite display area tovisually indicate that it is an audition set. The user selectable UIitem of some embodiments enables the opening and closing of a selectionarea. In some embodiments, a selection area displays all the media clipsthat are in an audition set. Some embodiments display the media clips inthe selection area in a carousel-like view (also referred to as a coverflow view). Other embodiments, however, may display the media clipsdifferently in the selection area. In addition, the media editingapplication of some embodiments allows the user to scroll through themedia clips displayed in the selection area.

DETAILED DESCRIPTION

In the following detailed description of the invention, numerousdetails, examples, and embodiments of the invention are set forth anddescribed. However, it will be clear and apparent to one skilled in theart that the invention is not limited to the embodiments set forth andthat the invention may be practiced without some of the specific detailsand examples discussed.

For a media editing application that creates composite presentations,some embodiments of the invention provide a novel auditioning tool thatallows a user to examine and maintain several different media clips thatare candidates for addition at or near a particular location in acomposite display area (also referred to as “candidate media clips”) andto select one of the media clips to be included in the compositepresentation.

A media clip in some embodiments is a piece of media content. Examplesof types of media content include audio data, video data, audio andvideo data, text data, image/picture data, and/or other media data. Insome embodiments, a media clip can be a video clip or an audio clip. Inother embodiments, a media clip can be a video clip, an audio clip, anaudio and video clip, a sequence of media clips (also referred to as acomposed media clip or a media clip sequence), a text clip, a textoverlay, a still image or picture, or any other type of media clip thatcan be used to create a composite presentation. In this application, amedia clip may also refer to the graphical representation of the mediaclip in the GUI of a media editing application of some embodiments.

For media content that have a temporal component (e.g., audio mediaclips, video media clips, audio and video media clips, etc.), the mediacontent is further defined by an in point and an out point with respectto a source media file. In some such embodiments, the source media fileis stored on the computing device on which the media editing applicationexecutes or on a computing device to which the media editing applicationhas access. A media clip's in and out points define its start and endpoint with respect to the source media file.

The in and out points of a media clip can be defined to be an entiresource media file or a portion of the source media file in someembodiments. Several media clips can define in and out points withrespect to the same source media file with each of the media clipshaving different media content. For instance, the in and out points of amedia clip can be defined to be the first half of a source media filewhile the in and out points of another media clip can be defined to bethe latter half of the source media file.

For some embodiments of the invention, FIG. 1 conceptually illustrates agraphical user interface (“GUI”) 100 of a media editing application withan auditioning tool of some embodiments. Specifically, this figureillustrates the GUI 100 at six different stages 105-130 in order to showthe creation of an audition set that includes three media clips. Anaudition set, in some embodiments, includes two or more media clips thatare specified as candidates for addition at a particular location in acomposite display area to specify a description of a composite mediapresentation. In some embodiments, an audition set is also referred toas a “stack” or an “audition stack.” Each of these stages will befurther described below after an introduction of the elements of the GUI100.

As shown in FIG. 1, the GUI 100 includes a media library 145, acomposite display area 135, a preview display area 140, and a menu bar150. The preview display area 140 displays a preview of a compositepresentation that the application creates by compositing several mediaclips. The menu bar 150 provides several grouped sets of menu commandsand options for the media editing application. In addition, this figureillustrates a cursor 160 for providing feedback to a user and operatingvarious selection buttons and other controls included in the GUI 100.The cursor 160 also allows a user to select or manipulate variousobjects (e.g., representations of media content) that are included inthe GUI 100. One of ordinary skill will recognize that, while a cursoris shown in FIG. 1 as well as many of the figures below, someembodiments display the GUI on a touchscreen device that enables theuser to control the GUI items without a cursor. Thus, when a selectionoperation is referred to as a “click operation” below, while shown usinga cursor, such selection operations may also be performed through atouch or “tap” of a touchscreen. Similarly, drag operations (e.g.,click-and-drag, drag-and-drop) can be performed through dragging afinger along a touchscreen in addition to the illustrated operationsinvolving a cursor. In addition, some embodiments displayed on atouchscreen will also display the cursor.

The media library 145 (also referred to as an “organizer display area”)is an area in the GUI 100 through which the application's user canselect media clips to add to a presentation that the user is compositingwith the media editing application. In addition, the media library 145of some embodiments is also used for other purposes, such as organizingmedia clips and/or compositing media clips, as described in furtherdetail below. In the example of FIG. 1, the media clips in the medialibrary 145 are represented as thumbnails that can be selected and addedto the composite display area 135 (e.g., through a drag-and-dropoperation or a menu selection operation). The clips in the media library145 may also be represented as a list, a set of icons, or some otherrepresentation that allows a user to view and select the various mediaclips in the media library 145. In some embodiments, the media library145 may include audio clips, video clips, audio and video clips, textoverlays, pictures, sequences of media clips, and/or other media clips.

The composite display area 135 provides a visual representation of thecomposite presentation being created by the user. Specifically, itdisplays one or more geometric shapes that represent one or more mediaclips that are part of the composite presentation. Media clips that arepart of the composite presentation are referred to below as “committedmedia clips.” As further described below, the media editing applicationof some embodiments allows media clips to be added to the compositedisplay area as candidate media clips. In some embodiments, candidatemedia clips are media clips that are candidates for adding to thecomposite presentation as they have not yet been added to the compositepresentation.

In some embodiments, the composite display area 135 specifies adescription of a composite presentation (also referred to as a“composite media presentation” or a “composite representation”). Asshown in FIG. 1, the composite display area 135 includes a centralcompositing lane 155 that spans a timeline and displays a graphicalrepresentation of the composite presentation (also referred to as a“composite representation”) by displaying media clips that form thecomposite presentation. One or more media clips can be placed on thecentral compositing lane 155. In some embodiments, no two committedmedia clips can overlap on the central compositing lane 155.

Furthermore, media clips can be placed (“anchored”) off of media clipsplaced in the central compositing lane 155 in regions above and below(not shown) the central compositing lane 155. Media clips placed in suchregions are referred to as “anchored media clips.” As an example, FIG. 1shows a media clip (“Clip B”) that is anchored off of another media clip(“Clip A”) in the composite display area 135. In some embodiments,several horizontal areas that span the timeline form quasi-tracks thatare also referred to as “anchor lanes.” In some of these embodiments,media clips can be placed in these anchor lanes to anchor off of mediaclips in the central compositing lane 155. Instead of, or in conjunctionwith, having several levels of media clips that anchor off the centralcompositing lane 155, some embodiments allow media clips to be placed inthese anchor lands and to be anchored off of other anchored media clipsplaced in these anchor lanes.

As shown, media clips may be displayed with different appearances indifferent areas of the GUI 100. For instance, the media clips in themedia library 145 in this example are represented using a thumbnail view(i.e., media clips are represented using a set equally-sized images)while the media clips in the composite display area 135 are representedusing a timeline view (i.e., media clips are represented using a set ofrectangular representations where the horizontal length of the rectangleprovides a visual indicator of the length or duration of the associatedmedia clip).

As mentioned above, an audition set includes two or more media clipsthat are specified as candidates for addition at a particular locationin a composite display area in some embodiments. In some embodiments,one of the media clips in an audition set is selected as the “activepick” of the audition set. An active pick is a media clip in an auditionset that is specified to interact with the media editing application. Assuch, the characteristics and attributes (e.g., graphicalrepresentation, effects, associated keywords, markers, etc.) of theactive pick are used when the audition set interacts with the mediaediting application. For instance, the graphical representation of theactive pick is used as the graphical representation of the audition set(e.g., a thumbnail view in the media library 145 or a media clip view inthe composite display area 135). As another example, the media contentof the active pick is displayed when a playback or skim operation isperformed on the audition set. In yet another example, the keywordsassociated with the active pick are used to determine whether theaudition set should be returned as part of a result of a keyword searchperformed on media clips. In some embodiments, when an edit operation isperformed on the audition set, the operation is performed on only theactive pick. In some embodiments, however, some or all of the editoperations that can be performed on the audition set are performed onall of the media clips in the audition set.

Different embodiments provide different methods for selecting an activepick when an audition set is initially created. For example, someembodiments select a random media clip in the audition set as the activepick. Other embodiments select a media clip in the audition set based onsome criteria, such as media clip duration, media clip creation time,order of media clip selection (e.g., first selected, last selected) whencreating the audition set, location of media clips (e.g., set the mediaclip in the composite display area 135 as the active pick), etc. Othermethods for determining which media clip to select as the active pickare possible.

The operation of the GUI 100 will now be described by reference to thestate of this GUI during the six stages 105-130 that are illustrated inFIG. 1. In the first stage 105, the composite display area 135 displaysa composite presentation that includes media clips that span along atimeline. A user might have added these media clips to the compositepresentation in a current editing session or by opening a compositeproject (also referred to as a “project”) that was defined in a previousediting session.

The second stage 110 of the GUI 100 shows several media clips selected.As shown, the media clips 165 and 170 in the media library 145 and mediaclip 175 in the composite display area 135 have been selected (e.g.,through a cursor click, a touch click), as indicated by the bolding ofthe borders of the media clips. In some embodiments, the selections areperformed individually while an input, such a hotkey or keystroke, ispressed and held.

The second stage 110 of the GUI 100 also displays a menu 180 thatincludes a user selectable “Create Stack” option and other userselectable options (not shown). The “Create Stack” option of someembodiments that is included in the menu 180 is for invoking thecreation of an audition set that includes the media clips that areselected (the media clips 165-175 in this example) when the “CreateStack” option is selected. Different embodiments of the menu 180 mayinclude different numbers of different user selectable options forperforming different functions. In some embodiments, the menu 180 isinvoked by selecting the “Stacks” option in the menu bar 150 through acursor click operation using the cursor 160. Some embodiments provideother ways to invoke the menu 180 as well. For instance, some of theseembodiments allow the user to invoke the menu 180 using a hotkey, akeystroke, a series of keystrokes, a combination of keystrokes, a touchoperation for a touchscreen device, or any other method to invoke themenu 180. The second stage 110 also illustrates the “Create Stack”option being selected through a cursor click operation using the cursor160.

The third stage 115 illustrates the GUI 100 after the creation of anaudition set 185 that includes the media clips 165-175. As shown, a userselectable user interface (“UI”) item 190 is displayed on the auditionset 185 to visually indicate that the audition set 185 displayed in thecomposite display area 135 is an audition set. The user selectable UIitem 190 of some embodiments enables the opening and closing of aselection area, as described in further detail below. Differentembodiments use different representations of the user selectable UI item190 to visually indicate that the audition set 185 is an audition set.For example, some embodiments may display a different geometric shape,text, or any other appropriate visual indicator. The third stage 115illustrates the selection of the UI item 190 through a cursor clickoperation using the cursor 160. In some embodiments, a touch operationcan be used for a touchscreen device.

The fourth stage 120 illustrates the GUI 100 at a stage after theselection of the user selectable UI item 190. As shown, a selection area192 (also referred to as a “selection display area”) that includes ascroll bar 194 is displayed (e.g., opened) in the GUI 100. In someembodiments, the selection area 192 is displayed in the GUI 100 shortlyafter the selection of the user selectable UI item 190. Some embodimentsprovide other mechanisms for invoking the display of the selection area192. For example, some of these embodiments allow the user to invoke theselection area 192 using a hotkey, a keystroke, a series of keystrokes,a combination of keystrokes, an option selected from a pop-up orpull-down menu, a touch operation for a touchscreen device, or any otherappropriate method to invoke the display of the selection area 192.

In some embodiments, the selection area 192 displays all the media clipsthat are in an audition set. For example, since the audition set 185includes the media clips 165-175, the selection area 192 displays thosemedia clips in the selection area 192. Some embodiments display themedia clips in the selection area 192 in a carousel-like view (alsoreferred to as a cover flow view) as illustrated in this example. Otherembodiments, however, may display the media clips differently in theselection area 192. For instance, some embodiments may display the mediaclips as text, icons, or any other visual representation of the mediaclips. Further, some embodiments may display the media clips indifferent views, such as a horizontal view, a vertical view, or othertypes of views that allow a user to scroll through the media clips.

The scroll bar 194 of some embodiments allows the user to scroll throughthe media clips displayed in the selection area 192. As shown, the userselectable left arrow UI item displayed in the scroll bar 194 is forscrolling the media clips displayed in the selection area 192 from leftto right. The user selectable right arrow UI item is similar to the leftarrow except it is for scrolling the media clips displayed in theselection area 192 from right to left. Also, the scroll bar 194 includesa position indicator to indicate the relative position of the media clipthat is displayed at or near the middle of the selection area 192 amongthe other media clips. In some embodiments, the user can also select anddrag (e.g., through a click-and-drag operation using the cursor 160) theindicator along the scroll bar 194 to scroll through the media clipsdisplayed in the selection area 192. Other embodiments provide otherways of scrolling through the media clips, such as using a hotkey, akeystroke, a series of keystrokes, a combination of keystrokes, anoption selected from a pop-up menu or pull-down menu, a touch operationfor a touchscreen device, or any other appropriate way to invoke ascrolling operation.

As shown in the fourth stage 120 of FIG. 1, an indicator 196 (e.g., abadge) for indicating that a media clip is an active pick (and thus acommitted media clip in some embodiments) is displayed on the thumbnailrepresentation of the media clip 175. As mentioned above, differentembodiments provide different methods for selecting an active pick whenan audition set is created. In this example, the media clip that is partof the composite presentation (the media clip 175 in this example) isselected as the active pick, as illustrated by the indicator 196displayed in the thumbnail representation of the media clip 175. Someembodiments set the last media clip selected before creating theaudition set as the active pick while other embodiments set the firstmedia clip selected as the active pick. Although this figure illustratesone way of indicating that a media clip in the audition set is theactive pick, different embodiments indicate that a media clip is anactive pick differently, such as highlighting the border of the mediaclip, displaying a label on the media clip, etc.

At the fifth stage 125, the GUI 100 shows the media clips are beingscrolled through the selection area 192. This stage shows a selection ofthe right arrow of the scroll bar 194 being selected through a cursorclick operation using the cursor 160, as illustrated by a change in theappearance of the right arrow. As shown in the selection area 192, themedia clips 165 and 175 have scrolled right to left and the indicator inthe scroll bar 194 has also changed positions accordingly. Although thisexample illustrates scrolling through the media clips displayed in theselection area 192 using the arrows of the scroll bar 194, the indicatorof the scroll bar 194 can be used to scroll through the media clipsdisplayed in the selection area 192 in some embodiments, as previouslymentioned above.

The sixth stage 130 of the GUI 100 shows the media clips 165-175displayed in the selection area 192 after they have been scrolledthrough from right to left. At this stage, the media clip 170 isdisplayed in the middle of the selection area 192.

I. Creating an Audition Set

As mentioned above, an audition set of some embodiments is defined astwo or more media clips that are specified as candidates for addition ata particular location in a composite display area. An audition set ofsome embodiments can include several of the same type of media clips orseveral different types of media clips. The following FIGS. 2-4conceptually illustrate several different examples of such auditionsets.

FIG. 2 illustrates an example audition set 200 that includes severalvideo clips. For this example, the audition set 200 includes four videoclips 205-220. As shown, the graphical representation of the auditionset 200 is the thumbnails of each of the four video clips 205-220stacked on top of each other in an offset manner. This graphicalrepresentation is just one of many possible representations. Forexample, some embodiments may graphically represent the audition set 200as a single thumbnail (e.g., the thumbnail of the active pick) with anindicator displayed on the thumbnail to indicate that it is an auditionset.

This figure also shows an exploded view 225 of the individual mediaclips in the audition set 200. As illustrated by their thumbnailrepresentations, the video clip 205 includes video content of boatssailing on the ocean, the video clip 210 includes video content of anumbrella under the sun, the video clip 215 includes video content of agolfer hitting a golf ball towards a hole, and video clip 220 includesvideo content of a person flying an airplane in the sky. Each of thevideo clips 205-220 is a candidate video clip for inclusion at aparticular location in the composite display area 135. For instance, thevideo clips 205-220 might be different introductory scenes of a moviepresentation.

FIG. 3 illustrates an example audition set 300 that includes severalaudio clips. Specifically, the audition set 300 includes four audioclips 305-320. Similar to the audition set 200, the graphicalrepresentation of the audition set 300 is the thumbnails of each of thefour audio clips 305-320 stacked on top of each other in an offsetfashion.

In an exploded view 325 of the audition set 300, the thumbnailrepresentation of each of the audio clips 305-320 is individually shown.For this example, the thumbnail representation of each of the audioclips 305-320 is of a waveform of a portion or all of the audio clip'saudio content. Other embodiments may use different graphicalrepresentations for the audio clips 305-320, such as an image thatindicates the audio file format (e.g., ACC, ALAC, MP3, WAV, etc.) of theaudio content. Accordingly, the audio clips 305-320 are candidate audioclips for inclusion at a particular location in a composite displayarea. For example, the audio clips 305-320 might be different soundbackground music for a scene in a movie presentation.

The audition sets described by reference to FIGS. 2 and 3 include thesame type of media clip. An audition set in some embodiments can includedifferent types of media clips. FIG. 4 illustrates an example of such anaudition set. This figure shows an audition set 400 that includes fourmedia clips 405-420. Like the audition sets 200 and 300, the graphicalrepresentation of the audition set 400 is the thumbnails of each of themedia clips 405-420 stacked on top of each other in an offset manner.

An exploded view 425 of the audition set 400 individually illustrateseach of the media clips 405-420. As shown, the media clip 405 is aneffect clip that is graphically represented by the name of the effect(“Blur” in this example). As mentioned above, a media clip can be asequence of media clips in some embodiments. In this example, the mediaclip 410 is a sequence of two video clips. Furthermore, the media clip415 is an audio clip and the media clip 420 is a video clip. Thus, themedia clips 405-420 of the audition set 400 are each candidate mediaclips for inclusion at a particular location in a composite displayarea.

The above described FIGS. 2-4 show examples of an audition set of fourvideo clips, an audition set of four audio clips, and an audition set offour different types of media clips. However, one of ordinary skill inthe art will realize that an audition set can include a different numberof media clips that can each be any number of different types of mediaclips. For instance, an audition set can include a sequence of videoclips, a sequence of audio clips, a sequence of effect clips, a sequencethat includes audio and video clips, among other media clips.

Moreover, although many of the examples described above and belowillustrate an audition set that includes two or more media clips, someembodiments provide the ability to create an audition set that includesone media clip (e.g., an audio clip, a video clip, etc.). For instance,a user might have a scene of a composite presentation that the user doesnot like, but the user has not re-shot the scene. In these instances,the user can create an audition set (e.g., by selecting the media clipof the scene in the composite display area and selecting the “CreateStack” option illustrated in FIG. 1) that includes just the media clipof the scene that the user does not like, with the intention of laterreshooting the scene and adding those reshoots to the audition set toevaluate and examine which one the user likes. In this manner, the usercan user the audition set to hold the place in the compositepresentation even though the user does not like the scene.

Continuing with the example, after reshooting the scene, the user canadd those reshoots to the audition set. The user might like one of thereshoots of the scene, but the user might change the scene to adifferent one. Here, the user can remove all the media clips from theaudition set except the one the user likes, resulting in an audition setthat includes one media clip. However, the user might not delete theaudition set so that the user can later add the different scene to theaudition set in case the user wants to change the scene.

In another example, the user may want to add a scene to a compositepresentation, but the user may not have the source files for the scene(e.g., the scene has not been shot). In such cases, the user mightcreate an audition set that includes a “blank” media clip (also referredto as a placeholder clip) to hold a location in the composite displayarea for the scene. The placeholder clips of some embodiments can have athumbnail representation that consists of an image that indicates to theuser the scene or shot that is desired or planned. For example, aplaceholder clip for a landscape scene might have a landscape stillimage as its thumbnail representation, a placeholder clip for a fightscene might have an image of boxing gloves as its thumbnailrepresentation, etc.

A. Operations to Create an Audition Set

FIG. 5 conceptually illustrates a data structure 500 of some embodimentsthat is stored for an audition set. As shown, the audition set datastructure 500 includes an audition set ID 505, a reference to activepick 510, and a set of media clip information 515.

The audition set ID 505 is a unique identification of the audition set.In some embodiments, the audition set ID 505 is unique within eachfunctional area (e.g., the media library 145 and the composite displayarea 135 described above by reference to FIG. 6) of a media editingapplication. In other embodiments, the audition set ID 505 is unique toa media project, or all projects edited by the media editingapplication.

The reference to active pick 510 points to information about one mediaclip in the set of media clip information 515. An example of a referenceto active pick 510 is a memory address (e.g., a memory address of alocation at which information about a media clip in the set of mediaclip information 515 is stored).

The media clip information 515 stores information about any media clipsthat have been added to the audition set. As shown, FIG. 5 alsoconceptually illustrates a data structure 550 of some embodiments thatis stored in the media clip information 515 for each media clip in theaudition set. In some embodiments, rather than storing the media clipinformation 515 directly in the audition set data structure 500, themedia editing application stores a reference to a media clip datastructure 550. As shown in this figure, the media clip data structure550 includes a media clip ID 555, a media clip name 560, a poster frame565, a reference to source file 570, and in and out points 575 and 580within the source file.

The media clip ID 555 is a unique identification of the media clip.Similar to the audition set ID 505 mentioned above, the media clip ID555 in some embodiments is unique within each functional area of a mediaediting application while in other embodiments, it is unique to themedia project or all projects within the media editing application.

The media clip name 560 is a secondary identification of the media clip.In some embodiments, it is the file name of a media source file (e.g.,“movie1.mov”, “movie2.avi”, etc.). When a media clip is duplicated in adisplay area in some such embodiments, the duplicate copies of the twomedia clips have the same clip name but have different media clip IDs.

The poster frame data element 565 stores the location of the posterframe (i.e., the representative thumbnail that is displayed in the medialibrary 145 to represent the media clip) when the media clip is a videoclip, an audio video clip, or a sequence of video and/or audio and videoclips. In some embodiments, the poster frame of a media clip is thefirst frame of the media clip by default. For audio clips, someembodiments store a portion of the clip for which the media editingapplication displays a waveform in the thumbnail representation of theclip.

The reference to source file 570 points to a location (e.g., on a localor network storage) at which the media source file (e.g., an audio file,video file, an audio and video file, etc.) is stored. An example of areference to source file is a memory address or a file directorystructure location and a file name. The in and out points 575 and 580refer to points (e.g., timecodes) within the source file at which themedia clip starts and stops. The in and out points could define themedia clip as the entirety of the source media file, or only a portionof the source media file (e.g., three seconds of a ten second videofile).

As mentioned above, the media clips of some embodiments include audioclips, video clips, audio and video clips, sequences of media clips, andeffect clips, among other types of media clips. The media clip datastructure for a sequence of media clips is different in someembodiments. For example, the media clip data structure of some of theseembodiments includes references to multiple source files and thepositions of the media clips in the sequence. The media clip datastructure of other of these embodiments may include additionalinformation to define the sequence. In addition, although an auditionset of some embodiments has several attributes as described above, theaudition set of other embodiments may have more, fewer, or differentattributes.

As described above by reference to FIG. 1, an audition set of someembodiments may be created by selecting media clips in the media library145 and the composite display area 135 and selecting an option from apull-down menu. However, other techniques for creating an audition setare possible. The following figures illustrate different techniques forcreating an audition set in some embodiments.

FIG. 6 conceptually illustrates another method of creating an auditionset using the GUI 100 of some embodiments. Specifically, FIG. 6illustrates the GUI 100 at four different stages 605-620 that show thecreation of an audition set by dragging a media clip from the medialibrary onto a clip in the timeline.

In the first stage 605, the GUI 100 shows a selection of the media clip165 through a click operation using the cursor 160. Similar to FIG. 1,described above, the composite display area 135 displays a compositepresentation that includes media items that span along a timeline that auser might have added to the composite presentation in a current editingsession or by opening a composite project that was defined in a previousediting session.

The second stage 610 displays the GUI 100 after the media clip 165 inthe media library 145 has been selected and dragged (e.g., through adrag-and-drop operation using the cursor 160) towards a media clip 175displayed in the composite display area 135, as indicated by a dottedarrow. In this example, the media clip 175 is a committed item. Thisstage illustrates a dotted rectangle in the composite display area 135that indicates a location in the composite display area 135 to which theuser drags the media clip 165. When the media clip 165 is selected inthe second stage 605, the preview display area 140 displays thethumbnail image that represents the media clip 165. However, in someembodiments, the thumbnail representation of the media clip 165 is notdisplayed in the preview display area 140 when the media clip 165 isselected in the media library 145.

The third stage 615 shows the GUI 100 after the user has finisheddragging the media clip 165 from the media library 145 to the media clip175 in the composite display area 135. When the user finishes draggingthe media clip 165 into the composite display area 135, the mediaediting application automatically displays a menu 625 shortly thereafterin some embodiments. The menu 625 includes a user selectable “CreateStack” option as well as other user selectable options (not shown).Different embodiments of the menu 625 may include different numbers ofdifferent user selectable options for performing different functions.The “Create Stack” option invokes a command to create an audition setthat includes the media clip(s) that was selected and dragged into thecomposite display area 135 (the media clip 165 in this example) and themedia clip in the composite display area 135 on which the former wasdragged (the media clip 175 in this example). The third stage 615 alsoillustrates the selection of the “Create Stack” option through a clickoperation using the cursor 160.

The fourth stage 620 illustrates the GUI 100 after the creation of anaudition set 630 that includes the media clips 165 and 175. As shown, auser selectable user interface (“UI”) item 190 is displayed on theaudition set 630 to visually indicate that the audition set 630displayed in the composite display area 135 is an audition set. The userselectable UI item 190 enables the opening and closing of a selectionarea, which is described in further detail below, in some embodiments.Different embodiments use different representations of the userselectable UI item 190 to visually indicate that the audition set 630 isan audition set. For example, some embodiments may display a differentgeometric shape, text, or any other appropriate visual indicator. Asillustrated in this stage, the GUI 100 displays content of the activepick of the audition set 630 in the preview display area 140 when thecreation of the audition set 630 is completed. In other embodiments, thecreation of the audition set does not affect the preview display area.

In some instances, a user of a media editing application may wish toaudition different versions of the same media clip. For example, theuser may wish to evaluate and examine how a media clip with different inand out points, durations, effects, etc., appears in a particular partof a composite presentation. The following FIGS. 7 and 8 illustrateexample techniques for creating audition sets with multiple versions ofa media clip.

FIG. 7 conceptually illustrates creating an audition set using the GUI100 according to some embodiments of the invention. In particular, thisfigure illustrates the GUI 100 at four different stages 705-720 thatshow the creation of an audition set that includes a media clip and anew version (i.e., a duplicate) of that media clip. The first stage 705is the same as the first stage 605 shown in FIG. 6.

At the second stage 710, the GUI 100 illustrates a selection of a mediaclip in the composite display area 135. As shown, the media clip 175 isselected through a click operation using the cursor 160. The GUIindicates this selection by bolding the border of the representation ofmedia clip 175.

The third stage 715 illustrates the GUI 100 during the initiation of thecreation of an audition set. As shown, the GUI 100 at this stagedisplays a menu 725 that includes a user selectable “New Version” optionas well as other user selectable options (not shown). The “New Version”option of some embodiments invokes a command to create a new version ofa selected media clip (media clip 175 in this example) and an auditionset that includes the selected media clip and the new version of it. Insome embodiments, the menu 725 is invoked by selecting the “Stacks”option in the menu bar 150 through a click operation using the cursor160. Some embodiments also provide other methods for invoking the menu725. For instance, some of these embodiments allow the menu 725 to beinvoked using a hotkey, a keystroke, a series of keystrokes, acombination of keystrokes, or any other method to invoke a menu. Thethird stage 715 illustrates the “New Version” option being selectedthrough a click operation using the cursor 160.

The fourth stage 720 shows the GUI 100 after the creation of an auditionset 730 that includes the media clip 175 and a new, separate version ofthe media clip. As shown, the user selectable item 190 is displayed onthe audition set 730 to visually indicate that the audition set 730 isan audition set. In this example, the media editing application sets thenew version of the media clip 175 as the active pick when the auditionset 730 is created. Some embodiments define a new data structure for thenew version that has a different identifier but the same defininginformation (i.e., poster frame, source file, in and out points, etc.).The user can then edit one of the versions of the media clip (e.g.,modify the in and out points) while leaving the other version unchanged.

As the new version of the media clip 175 is the first such new versionof this media clip, the media editing application names the new versionusing the name of the media clip 175 appended with a label indicatingthe version number (“V1” in this example), as shown by the display of“Clip D V1” in the audition set 730. Subsequent versions of the mediaclip 175 are named with sequential version numbers (e.g., “Clip D V2,”“Clip D V3,” etc.) in some embodiments. Other embodiments may provideother ways of naming a new version of a media clip. Although thisexample illustrates that the newly created version is set as the activepick of the audition set 730, some embodiments set the original mediaclip 175 as the active pick of the audition set 730 (and the namedisplayed in the audition set 730 would remain as “Clip D”).

FIG. 8 illustrates an example of creating an audition set that includesa media clip and a version of the media clip with an effect applied. Asshown, FIG. 8 illustrates the GUI 800 at four different stages 805-820that show the creation of such an audition set. The GUI 800 is similarto the GUI 100 except the GUI 800 also includes an effects panel 825. Asshown, the effects panel 825 includes a “Video” tab for displaying aneffects panel for video effects and an “Audio” tab for displaying aneffects panel for audio effects. For this example, the “Video” tab isselected and the effects panel thus displays video effects. Inparticular, the effects panel 825 includes user selectable effect items830-840 and other user selectable effects (not shown). Each of the userselectable effects in the effects panel 825 causes the application ofone or more video effects to a media clip when selected. For instance,the effect item 830 applies a blur video effect, the effect item 835applies a black and white video effect, and the effect item 840 appliesa fade-in/fade-out video effect.

The first stage 805 illustrates the GUI 800 at the beginning of thecreation of an audition set. Specifically, a user has selected theeffect item 830 and drags the item (e.g., through a drag-and-dropoperation) using the cursor 160 towards the media clip 175 in thecomposite display area 135.

In the second stage 810, the user has finished dragging the effect item830 from the effects panel 825 to the media clip 175. When the userfinishes dragging the effect item 830 onto the media clip 175, the mediaediting application automatically displays a menu 625 shortlythereafter. The second stage 810 shows the selection of the “CreateStack” option through a click operation using the cursor 160. Thisselection invokes a command to create an audition set 845 that includesthe media clip 175 and a new version of the media clip 175 with theeffect of the effect item 830 (i.e., a blur effect) applied to it.

The third stage 815 illustrates the GUI 800 after the creation of theaudition set 845 is completed. As shown, the media editing applicationdisplays a user selectable UI item 190 in the audition set 845 tovisually indicate that the audition set 845 displayed in the compositedisplay area 135 is an audition set. In this example, the media editingapplication sets the new version of the media clip 175 that includes theblur effect as the active pick when creating the audition set 845. Someembodiments define a new data structure for the new version that has adifferent identifier but the same defining information (i.e., posterframe, source file, in and out points, etc.). Some embodiments alsostore the blur effect or a reference to the blur effect in the datastructure for the newly created media clip.

At the fourth stage 820, a user has selected the UI item 190 (e.g.,through a click operation using the cursor 160). As mentioned above, theUI item 190 enables the opening and closing of a selection area thatdisplays the media clips included in the associated audition set. Assuch, the GUI 800 now displays selection area 192. The selection area192 displays the media clip 175 and a media clip 850, which is the newlycreated version of the media clip 175 with the blur effect applied. Inthis example, the selection area 192 displays a label specifying thename of the media clip displayed at or near the center of the selectionarea 192. Because the media clip 850 is currently displayed in thecenter region of the selection area 192, a label displayed above themedia clip 850 specifies the name of the media clip 850 as “ClipD—Blur,” which is the name of the media clip 175 along with the effectapplied in clip 850.

FIG. 8 shows the creation of the audition set 845 by dragging anddropping a user selectable effect item from the effects panel 825 onto amedia clip in the composite display area 135. Some embodiments mayprovide other ways for the user to create the audition set 845. Forinstance, some embodiments allow the user to select the media clip 175in the composite display area 135 and invoke the creation of theaudition set 845 using a hotkey, a keystroke, a series of keystrokes, acombination of keystrokes, or any other appropriate way of invoking acommand.

Moreover, FIG. 8 shows the effects panel 825 with a user selectable“Video” tab and a user selectable “Audio” tab for displaying an effectspanel for video effects and an effects panel for audio effect,respectively. However, some embodiments of the effects panel 825 includeadditional and/or different user selectable tabs for displayingdifferent effects panels for different types of effects. In addition,while the effects included in the effects panel for the “Video” includea particular set of video effects, these example effects are onlyprovided for purposes of explanation; one of ordinary skill in the artwould recognize that any number of different video effects can beincluded in the “Video” effects panel, such as a Gaussian blur effect, aborder effect, a direction blur effect, etc.

The above figures illustrated various different ways to create a newaudition set. FIG. 9 conceptually illustrates a process 900 of someembodiments for creating a new audition set. The process 900 begins byreceiving (at 905) input to associate media clips as an audition set.This input may be received from a selection of a drop-down menu in someembodiments, as shown in FIG. 1 or FIG. 7. The selection input may befrom a cursor controller (e.g., a click input), through a touchscreen(e.g., touching a menu option), from a keyboard, etc. Some embodimentsreceive the input from a pop-up menu that appears automatically when amedia clip or an effect is dragged and dropped (e.g., with a cursorcontroller, through a touchscreen, etc.) onto another media clip, asshown in FIG. 6 or FIG. 8. In some embodiments, the input consists of auser dragging and dropping media clips within the media library, asshown below by reference to FIG. 27.

The process then identifies (at 910) a set of media clips to associateas the audition set. The media clips may include video clips (as inFIGS. 1, 6, etc.) as well as other clips such as audio clips, effectsclips, or sequences of video clips, which are described in furtherdetail below. Some embodiments associate all selected clips at the timethe user input is received. In some cases, when a clip is dragged ontoanother clip, these two clips are associated. Some situations (e.g., asshown in FIG. 7) associate a media clip with a duplicate of itself as anaudition set.

Next, the process 900 identifies (at 915) a media clip from the auditionset to set as the active pick. As mentioned above, the active pick of anaudition set is the media clip that interacts with the compositepresentation. As examples, when a user adds an audition set to thecomposite presentation, the media editing application adds the activepick to the composite project. When edits (e.g., trim edits) areperformed on the audition set, the editing application applies the editsto the active pick. When one of the media clips being associated isalready in the composite display area and the rest are clips from themedia library, some embodiments automatically set the clip in thecomposite display area as the active pick. When the creation of theaudition set involves the creation of a duplicate of a clip (or of aportion of a clip, or a duplicate with an effect), some embodiments setthe new clip as the active pick while other embodiments set the originalclip as the active pick.

The process then creates (at 920) a data structure for the audition set.FIG. 5 illustrates an example of such a data structure 500. As describedabove, the data structure includes at least a reference to each mediaclip in the data structure and an indication of the active pick. Someembodiments include more information about the audition set, such as itslocation in the timeline of the composite display area.

The process also displays (at 925) the audition set in the GUI. In theexamples shown in the figures above, the media editing applicationdisplays an indicator within the media clip in the composite displayarea to indicate that the media clip is the active pick of an auditionset. In some embodiments, as shown below by reference to FIG. 27, when auser associates clips in the media library as an audition set, the clipsare displayed as a stack with an audition set indicator. After creatingthe data structure and displaying the audition set, the process ends.

B. Adding a Clip to an Audition Set

Once an audition set is created, users can add additional media clips tothe audition set. FIG. 10 illustrates the addition of a media clip to anaudition set using the GUI 100 of some embodiments. In particular, thisfigure illustrates the GUI 100 at four different stages 1005-1020 thatshow the addition of a media clip to an audition set displayed in thecomposite display area 135 of some embodiments. The GUI 100 in thisfigure continues from the last stage 620 illustrated in FIG. 6, at whichpoint an audition set 630 is created. The first stage 1005 shows theselection of the audition set 630, displayed in the composite displayarea 135, through a cursor control operation using the cursor 160.

The second stage 1010 of the GUI 100 shows a selection of a media clip1025 in the media library 145 through a click operation (e.g., acontrol-cursor-click operation) using the cursor 160. When the userselects media clip 1025, the preview display area 140 displays thethumbnail image that represents the media clip 1025. In someembodiments, such a selection of a media clip from the media librarydoes not affect the preview display area.

At the third stage 1015, the GUI 100 displays a menu 1030 that includesa user selectable “Add to Stack” option and other options (not shown).In this example, the user selectable “Add to Stack” option invokes anoperation to add a selected media clip(s) to a selected audition set(the media clip 1025 and the audition set 630 in this example). In someembodiments, the user invokes menu 1030 by selecting the “Stacks” optionin the menu bar 150 through a click operation (e.g., cursor clickoperation, touch operation, etc.). Other embodiments provide other waysto invoke the menu 1030. For instance, some embodiments allow the userto invoke the menu 1030 using a hotkey, a keystroke, a series ofkeystrokes, a combination of keystrokes, or any other appropriate methodto invoke a menu.

The fourth stage 1020 shows the GUI 100 after the completion of theaddition operation. As shown, the display of the audition set 630 in thecomposite display area remains unchanged. The audition set 630 stilldisplays the user selectable UI item 190 to visually indicate that themedia clip is an audition set. However, the media editing applicationmodifies the data structure for the audition set 630 to include themedia clip 1025.

FIG. 11 illustrates an alternative method of adding an item to anaudition set using the GUI 100 of some embodiments. Specifically, FIG.11 illustrates the GUI 100 at three different stages 1105-1115 that showthe addition of a media clip to an audition set displayed in thecomposite display area 135 according to some embodiments. Similar toFIG. 10, the GUI 100 in this figure continues from the last stage 620 ofFIG. 6. The first stage 1105 of the GUI 100 shows the selection anddragging of media clip 1120 (e.g., through a drag-and-drop operation)from the media library 145 towards the audition set 630 in the compositedisplay area 135, as indicated by a dotted arrow.

The second stage 1110 shows the GUI 100 after the media clip 1120 hasbeen dragged and dropped on top of the audition set 630. At this stage,the GUI 100 also displays a menu 1125. When the user finishes draggingthe media clip 1120 into the composite display area 135, the mediaediting application automatically displays a menu 1125 shortlythereafter. As shown, the menu 1125 includes a user selectable “Add toStack” option and other user selectable options (not shown). Differentembodiments of the menu 1125 may include different numbers of differentuser selectable options for performing different functions. In thisexample, the “Add to Stack” option invokes a command to add the mediaclip(s) that was selected and dragged into the composite display area135 (the media clip 1120 in this example) and to the audition set in thecomposite display area 135 on which the former was dragged (the auditionset 630 in this example). The second stage 1110 also illustrates theselection of the “Add to Stack” option through a click operation usingthe cursor 160.

The third stage 1115 shows the GUI 100 after the completion of theaddition operation. As shown, the display of the audition set 630 in thecomposite display area remains unchanged. The audition set 630 stilldisplays the user selectable UI item 190 to visually indicate that themedia clip is an audition set. However, the media editing applicationmodifies the data structure for the audition set 630 to include themedia clip 1120.

FIGS. 10 and 11 illustrate two different ways to add a media clip to anaudition set through the composite display area 135. Other embodimentsallow a media clip to be added to an audition set through other elementsof the GUI 100 of some embodiments. For example, the following FIGS.12-14 illustrates several different ways to add a media clip to anaudition set through the selection area 192.

FIG. 12 illustrates another method of adding a media clip to an auditionset using the GUI 800 of a media editing application of someembodiments. This figure illustrates the GUI 800 at four differentstages 1205-1220 of the addition operation. In this example, the GUI 800includes the audition set 630 in the composite display area 135. Theaudition set 630 includes the media clips 165 and 175, as shown in FIG.6.

At the first stage 1205, the GUI 800 displays the selection area 192.The selection area 192 may have been invoked using methods such asperforming a click operation (e.g., cursor click operation, touch clickoperation, etc.) on the user selectable UI item 190, a hotkey, akeystroke, a series of keystrokes, a combination or keystrokes, etc., asdescribed above. As shown, the selection area 192 displays the mediaclips 175 and 165, which are part of the audition set 630. For thisexample, the selection area 192 displays a label that specifies the nameof the media clip displayed at or near the center of the selection area192. As the selection area currently displays media clip 175 in thiscenter region at this stage, a label that specifies the name of themedia clip 175, “Clip D,” is displayed above the media clip 175 in theselection area 192.

The second stage 1210 of the GUI 800 illustrates the selection anddragging of user selectable effect item 830 from the effects panel 825(e.g., through a drag-and-drop operation) towards the media clip 175using the cursor 160, as indicated by the dotted arrow. As describedpreviously, the effect item 830 applies a blur effect to a video clip.

The third stage 1215 shows the GUI 800 after the user has finisheddragging the effect item 830 onto the media clip 175 displayed in theselection area 192. When the user finishes dragging the effects item 830onto the media clip 175, the media editing application automaticallydisplays a menu 1230 shortly thereafter in some embodiments. As shown,the menu 1230 includes a user selectable “Add Version with Effect”option along with other user selectable options (not shown). The thirdstage 1215 also illustrates the selection of the “Add Version withEffect” through a cursor click operation using the cursor 160. Thisselection invokes a command to add to the audition set a new version ofthe media clip 175 with the effect item 830 (i.e., a blur effect)applied.

The fourth stage 1220 shows the GUI 800 after the addition of a newmedia clip 1235. In this stage, the selection area 192 displays the newmedia clip 1235 at or near its center, the media clip 175 to the leftside of the selection area 192, and the media clip 165 on the right sideof the selection area 192. In other embodiments, the media clips of theaudition set 630 are displayed in the selection area 192 differently.For instance, some of these embodiments display the newly added mediaclip 1235 at one end (the left or the right) of the other media clips(the media clips 165 and 175 in this example).

Moreover, the media clip 1235 displays the indicator 196 that indicatesthat the media clip 1235 is the active pick of the audition set 630. Asillustrated in this example, the newly added media clip 1235 isautomatically set as the active pick of the audition set 630 upon itsaddition to the audition set 630. In some embodiments, the media editingapplication does not change the active pick when adding the media clip1235 is added to the audition set 630. In addition, a label specifyingthe name of the media clip 1235 is displayed above the media clip 1235in the selection area 192. Similar to the naming convention describedabove by reference to FIG. 8, the name used for the new media clip 1235,“Clip D—Blur,” is the name of the effect (i.e., a blur effect) appendedto the name of the media clip 175.

Although FIG. 12 shows a blur effect applied to the media clip 175 ofthe audition set 630 through the selection area 192, one of ordinaryskill will realize that this figure merely illustrates one example andany other effect can be applied to any media clip of the audition set630 using the same or similar technique illustrated by FIG. 12.

FIG. 13 illustrates another addition of a media clip to an audition setusing the GUI 100 of some embodiments. This figure illustrates the GUI100 at four different stages 1305-1320 that show the addition of a mediaclip to an audition set through a selection area 1325 of someembodiments. For this example, the GUI 100 continues from the last stage620 illustrated in FIG. 6, at which the audition set 630 is created. Thefirst stage 1305 of the GUI 100 illustrates the selection of userselectable UI item 190 through a click operation using the cursor 160,which causes a change in the appearance of the UI item 190.

The second stage 1310 illustrates the GUI 100 after the selection of theUI item 190. The GUI 100 now displays a selection area 1325 that issimilar to the selection area 192 except that the selection area 1325includes user selectable UI items 1330-1340. That is, the selection area1325 displays an active pick 175 (indicated by the indicator 196) and acandidate media clip 165. In this example, the user selectable UI item1330 (e.g., “Duplicate” button 1330) invokes the addition of a newversion (i.e., duplicate) of a selected media clip displayed in theselection area 1325, the user selectable UI item 1335 (e.g., “Cancel”button 1335) cancels any operations performed in the selection area1325, and the user selectable UI item 1340 (e.g., “Done” button 1340)saves any operations performed in the selection area 1325.

The third stage 1315 illustrates the GUI 100 at the start of theduplicate media clip addition operation. As shown, the user selects theuser selectable UI item 1330 (“Duplicate”) through a click operationusing the cursor 160. Some embodiments allow the user to invoke theoperation using other methods. For instance, in some such embodiments,the user can invoke the duplication operation using a hotkey, akeystroke, a series of keystrokes, or a combination of keystrokes. Othermethods are also possible.

The fourth stage 1320 shows the GUI 100 after the completion of theaddition operation. In this example, the addition operation adds a newmedia clip 1345 to the audition set 630 and displays the new clip in theselection area 1325. The new media clip 1345 has the same parameters(i.e., source file, in and out points, poster frame, etc.) as the mediaclip 175. As shown, the media editing application displays the newlycreated duplicate media clip 1345 in the middle of the selection area1325, and the media clip 175 on the left side of the selection area1325. The GUI adjusts the scroll bar indicator to the middle of thescroll bar accordingly.

In addition, the media editing application sets the new media clip 1345as the active pick for the audition set 630, as shown by the indicator196 displayed in representation of the media clip 1345. However,different embodiments handle the addition of a duplicate media clip toan audition set differently. For example, some embodiments designate thenew media clip as the active pick but move and display the previouslycentered media clip to the right side of the selection area. Otherembodiments may not change the active pick of the audition set, anddisplay the duplicated media clip on the left side of the selectionarea.

FIG. 14 illustrates the addition of a media clip to an audition setusing the GUI 100 according to some embodiments of the invention. LikeFIG. 13, FIG. 14 illustrates the addition of a new version of a mediaclip to the audition set. This figure shows the GUI 100 at fourdifferent stages 1405-1420 that show the addition of a media clip to anaudition set through the selection area 192. In this example, the GUI100 continues from the last stage 620 shown in FIG. 6, at which theaudition set 630 is created. The first stage 1405 of the GUI 100 is thesame as the first stage 1305, described above.

The second stage 1410 illustrates the GUI 100 after the selection of theUI item 190. The GUI 100 now displays the selection area 192. As shown,the selection area 192 displays the media clips 165 and 175. Inaddition, the indicator 196 is displayed in the media clip 175 toindicate that the media clip 175 is the active pick of the audition set630. In addition, this stage illustrates the selection of media clip 175through a cursor click operation using the cursor 160.

The third stage 1415 shows the GUI 100 displaying a menu 1425 thatincludes a user selectable “New Version” option in addition to otheruser selectable options (not shown). The “New Version” option of someembodiments invokes a command to create a new version of a media clip(media clip 175 in this example) selected in the selection area 192 andto add the newly created clip to the audition set shown in the selectionarea (audition set 630 in this example). In some embodiments, the menu1425 is invoked by selection of the “Stacks” option in the menu bar 150through a click operation (e.g., a cursor click operation, touch clickoperation, etc.). However, some embodiments provide other ways to invokethe menu 1425. For example, some such embodiments allow the user toinvoke the menu 1425 using a hotkey, a keystroke, a series ofkeystrokes, a combination of keystrokes, or any other appropriate methodto invoke a menu. The third stage 1415 shows the selection of the “NewVersion” option through a click operation using the cursor 160.

The fourth stage 1420 illustrates the GUI 100 after the addition of amedia clip 1430, which is a new version of the media clip 175, to theaudition set 630. As shown, the GUI 100 displays the new media clip 1430at or near the center of the selection area 192, the media clip 175 onthe left side of the selection area 192, and the media clip 165 on theright side of the selection area 192. Also, the media editingapplication displays indicator 196 on the media clip 1430 to indicatethat the new media clip is now the active pick of the audition set 630.As mentioned above, when a media clip is added to an audition set, someembodiments do not change the active pick to the newly added media clip.

The above figures illustrated a variety of different ways to add a mediaclip to an already-created audition set. FIG. 15 conceptuallyillustrates a process 1500 of some embodiments for adding a media clipto an audition set. The process 1500 begins by receiving (at 1505) inputto add a media clip to an audition set. As illustrated in the variousfigures above, this input may be received in a variety of differentways. For instance, the input may be received through a selection of anitem in a drop-down menu (e.g., as shown in FIG. 10 or FIG. 14), aselection of an item in a pop-up menu that appears automatically as aresult of a drag-and-drop operation (e.g., as shown in FIG. 11 or 12), aselection of a UI button (e.g., as shown in FIG. 13), or other userinput. The selection input may be received through a cursor controller(e.g., as click input or drag-and-drop input followed by click input),through a touchscreen (e.g., touching a menu option or dragging anddropping an item followed by touching a menu option), from a keyboard,etc.

The media clip added to the set may be any sort of media clip in someembodiments. While the examples above show video clips (that may includeeffects), some embodiments allow the user to create a heterogeneousaudition set that includes audio clips, sequences of media clips,effects clips, still images, text, etc.

The process then modifies (at 1510) the data structure of the auditionset to include the media clip. In some embodiments, this simply involvesadding a reference to a data structure of the media clip that alreadyexists. Some embodiments write the information describing the media clipinto the data structure for the audition set. Additionally, in somecases, a new media clip is created and thus a new data structure for themedia clip must also be created (e.g., in the example shown in FIG. 14).

Next, the process determines (at 1515) whether to set the newly addedmedia clip as the active pick of the set. In some embodiments, when analready-existing media clip is added to an already-existing auditionset, the audition set retains its current active pick. On the otherhand, when a new version of a media clip is added to an already-existingaudition set (e.g., a portion of the clip, the clip with an effectapplied, a duplicate of the clip), some embodiments set the new versionas the active pick for the audition set. When the newly added media clipshould be the new active pick for the audition set, the process modifies(at 1520) the data structure for the audition set to set the newly addedmedia clip as the active pick. In some embodiments, this simply involvesmodifying a reference to refer to one media clip instead of another.

The process then determines (at 1525) whether any modifications to theGUI are required by the change. When modifications are required, theprocess modifies (at 1530) the GUI as necessary. When the audition setis in the composite display area and the addition does not change theactive pick, some embodiments do not require any GUI modifications.However, when displaying the selection area of some embodiments, a newmedia clip appears in the selection area. The process may also need tomove the active pick indicator from one clip to another. The processthen ends.

C. Removal of a Clip from an Audition Set

The FIGS. 10-14 illustrate a variety of different ways to add a mediaclip to an audition set. In addition, some embodiments enable the userto remove one or more media clips from an audition set. The followingFIGS. 16 and 17 will describe examples of some such embodiments.

FIG. 16 illustrates the removal of a media clip from an audition setusing the GUI 100 of some embodiments. This figure illustrates the GUI100 at four different stages 1605-1620 that illustrate the removal of amedia clip from an audition set displayed in the composite display area135 of some embodiments. In this example, the GUI 100 displays theaudition set 185, which was created as illustrated in FIG. 6, in thecomposite display area 135. However, for purposes of explanation of theremoval operation, the audition set 185 represents a grouping of threemedia clips instead of two. The first stage 1605 of the GUI 100illustrates the selection of a user selectable UI item 190 through aclick operation using the cursor 160, as indicated by a change in theappearance of the UI item 190.

The second stage 1610 illustrates the GUI 100 after the selection of theUI item 190. The GUI now displays the selection area 192 displaying anaudition set 185. As mentioned, the audition set 185 in this examplerepresents a logical grouping of three media clips: clips 175, 165, and1625. The media clip 175 is the active pick for this audition set.

At the third stage 1615, the media clip 165 displayed in the selectionarea 192 has been selected (e.g., through a click operation such as acursor click operation, a touch click operation, etc.). The GUI 100indicates this selection through the bolded border of the thumbnailrepresenting media clip 165. The GUI 100 also displays a menu 1630 thatincludes a user selectable “Remove from Stack” option and other options(not shown) as well. The user selectable “Remove from Stack” optioninvokes an operation to remove one or more selected media clips (thesingle media clip 165 in this example) from the audition set displayedin the selection area 192. In some embodiments, the user invokes menu1630 by selecting the “Stacks” option in the menu bar 150 through aclick operation. Some embodiments provide other ways to invoke the menu1630. For example, some such embodiments allow the user to invoke themenu 1630 using a hotkey, a keystroke, a series of keystrokes, acombination of keystrokes, or any other appropriate method to invoke amenu.

The fourth stage 1620 illustrates the GUI 100 after the media editingapplication removes the media clip 165 from the audition set 185. Atthis stage, the audition set 185 represents a logical grouping of onlythe media clips 175 and 1625. As shown, the audition set 185 displayedin the composite display area 135 still displays the user selectable UIitem 190 to visually indicate that the media clip is an audition set, asmore than one media clip remains. When a user removes all but one mediaclip from an audition set, the audition set no longer exists as anassociated set of media clips, and media editing application removes thedata structure for the audition set, leaving only a standard media clipdata structure.

FIG. 17 illustrates another audition set removal operation using the GUI100 of some embodiments. FIG. 17 illustrates the GUI 100 at fourdifferent stages 1705-1720 that also show the removal from an auditionset displayed in the composite display area 135 of some embodiments.Similar to FIG. 16, the GUI 100 displays the audition set 185, which wascreated as illustrated in FIG. 6, in the composite display area 135. Thefirst and second stages 1705 and 1710 of the GUI 100 are the same as thefirst and second stages 1605 and 1610, respectively, described above byreference to FIG. 16. In these stages, the user selects item 190 inorder to open selection area 192 with the three media clips 175, 165,and 1625.

The third stage 1715 of the GUI 100 shows the user interaction resultingin the removal operation. Like the third stage 1615 illustrated in FIG.16, the media clip 165 is also selected for removal in this example. Asshown at this stage, the user selects and drags media clip 165 (e.g.,through a drag-and-drop operation) to an area in the GUI 100 outside ofthe selection area 192. While this stage illustrates the media clip 165dragged to a particular area outside of the selection area 192, someembodiments allow the user to drag the media clip 165 to any areaoutside of the selection area 192 to invoke its removal from theaudition set 185 in some embodiments.

At the fourth stage 1720, the media editing application has removed themedia clip 165 from the audition set 185. That is, the media clip 165 isno longer included in the logical grouping represented by the auditionset 185. Accordingly, at the fourth stage 1720, the GUI 100 no longerdisplays the media clip 165 in the selection area 192.

The examples illustrated in FIGS. 16 and 17 show different methods forremoving the media clip 165 from the audition set 185. One of ordinaryskill in the art will recognize that other media clips in the auditionset 185 can be removed in the same or similar fashion. Furthermore,these figures illustrate the removal of a single media clip from anaudition set. Some embodiments allow the user to select multiple mediaclips in the selection area 192 and remove all of the selected mediaclips from the audition set through a single invocation of a removaloperation.

Although not shown in FIGS. 16 and 17, some embodiments allow theremoval of the active pick of an audition. Different embodiments handlethe removal of the active pick in an audition set differently. Forinstance, some embodiments designate the next media clip displayed inthe selection area 192 as the active pick. Some embodiments randomlyselect a new media clip from the audition set as the active pick. Othermethods for determining the active pick for the audition set are alsopossible.

FIG. 18 conceptually illustrates a process 1800 of some embodiments forremoving a media clip from an audition set. As shown, the process 1800begins by receiving (at 1805) input to remove a media clip from anaudition set. As illustrated in the figures above, this input may bereceived in a variety of different ways. For instance, the input may bereceived through selection of an item in a menu (e.g., as shown in FIG.16), a drag-and-drop operation (e.g., as shown in FIG. 17), selection ofa UI button, or other user input. The selection input may be receivedthrough a cursor controller (e.g., as click input or drag-and-dropinput), through a touchscreen (e.g., touching a menu option or draggingand dropping an item), from a keyboard, etc.

The process then modifies (at 1810) the data structure of the auditionset to remove the media clip. In some embodiments, this simply involvesremoving a reference to a data structure for the media clip. When themedia clip data is part of the audition set data structure, someembodiments rewrite this information to a new location in the projectdata as a sole media clip and remove the information from the auditionset data structure.

The process then determines (at 1815) whether the removed media clip wasthe active pick. When this is the case, the process selects (at 1820) anew active pick and modifies the data structure for the audition set torefer to the new active pick. Some embodiments designate a media clip asan active pick based on an order of media clips within the audition set(e.g., the order in which the clips were added to the audition set),designate a random media clip from the audition set, or use othermethods.

Next, the process 1800 determines (at 1825) whether any modifications tothe GUI are required by the change. When modifications are required, theprocess modifies (at 1830) the GUI as necessary. When displaying theaudition set in the selection area, the media editing application nolonger displays the representation of the removed media clip after itsremoval. In some embodiments, a new media clip is brought to the centerof the selection area as well.

D. Creation of Audition Sets with Different Types of Media Clips

The examples described above illustrate different operations (creation,addition, and removal) applied to audition sets composed entirely ofvideo clips. However, as shown in FIG. 4, an audition set may includeaudio clips, effects clips, sequences, etc., in some embodiments.Moreover, many of the examples described above illustrate the creationof an audition set in the central compositing lane 155 of the compositedisplay area 135. Some embodiments also allow the user to create anaudition set in other areas of the composite display area 135, such asan anchor lane of the composite display area 135. The following figuresillustrate the creation of sequences involving additional types of mediaclips and through different areas of the GUI.

FIG. 19 illustrates the creation of an audition set that includes audioclips in an anchor lane of the composite display area 135 of GUI 100according to some embodiments. In this figure, the GUI 100 isillustrated at six different stages 1905-1930 that show the creation ofan audition set 1950. As shown, the media library 145 includes two audioclips 1935 and 1940, as indicated by the waveforms used for thegraphical representation of these clips. In this example, the media clip1945 displayed in the composite display area 135 is also an audio clip.

The first stage 1905 illustrates the selection of several mediaclips—specifically, audio clips 1935 and 1940 are selected, as indicatedby a bolding of the borders of the thumbnail representations of theseaudio clips 1935 and 1940. These audio clips have previously beenselected (e.g., through click operations such as cursor clickoperations, touch click operations, etc.). Further, this stage shows theselection of the media clip 1945, also indicated by a bolding of theborder of its graphical representation, in the composite display area135 through a click operation using the cursor 160.

Similar to the second stage 110 described above, the second stage 1910displays the menu 180. This stage also illustrates the selection of the“Create Stack” option through a cursor click operation using the cursor160. As mentioned above, the “Create Stack” option of some embodimentsinvokes the creation of an audition set with the selected media clips.As such, in this example, the selection of the “Create Stack” optioncauses the media editing application to create an audition set 1950having the media clips 1935, 1940, and 1945.

The third stage 1915 illustrates the GUI 100 after the creation of theaudition set 1950. As shown, the user selectable UI item 190 isdisplayed on the audition set 1950 to indicate that it is an auditionset. This stage also illustrates the selection of this UI item to invokethe display of selection area 192.

The fourth stage 1920 of the GUI 100 displays the selection area 192. Asshown, the selection area 192 displays the media clips 1935-1945. Asdescribed above by reference to FIG. 1, some embodiments set theselected media clip in the composite display area 135 as the active pickof an audition set upon creation of the audition set. Similarly, in thisexample, the media editing application sets the media clip 1945 as theactive pick of the audition set 1950 because it is the selected mediaclip in the composite display area 135. Accordingly, the indicator 196is displayed on the media clips 1945 to indicate that it is the activepick of the audition set 1950.

At the fifth stage 1925, the GUI 100 shows the media clips in theselection area 192 as a user scrolls through the clips in the same or asimilar manner as previously described above by reference to FIG. 1. Asshown, the user selects the right arrow through a click operation usingthe cursor 160 in order to scroll through the media clips 1935-1945 fromright to left. The sixth stage 1930 illustrates the GUI 100 after allthe media clips 1935-1945 have been scrolled through from right to left.As shown, the media clip 1935 is now displayed at or near the middle ofthe selection area 192.

As mentioned above, some embodiments can also include sequences of mediaclips in an audition set. While the composite display area is used tocomposite media clips in some embodiments, the media library of somesuch embodiments can also be used as a secondary area to composite mediaclips. For example, a user of the media editing application may wish tocreate sequences of media clips without having to select a particularlocation in the composite display area in which to place the sequence ofmedia clips. In this way, the user can create sequences of media clipsand then add them to the composite display area at a later time. FIGS.20A and 20B illustrate the creation of a sequence and subsequentcreation of an audition set that includes the sequence through the GUI100. As shown, these figures illustrate the GUI 100 at nine differentstages 2005-2045 that show the creation of a sequence and the creationof an audition set that includes the created sequence.

The first stage 2005 of the GUI 100 shows a selection of several mediaclips. In particular, this stage shows the selection of media clips 170and 2055 through a selection box operation using the cursor 160, asillustrated by the dotted box enclosing the media clips 170 and 2055.One of ordinary skill in the art will recognize that similar operationsmay be performed using a touchscreen or other input devices in order toselect multiple media clips.

At the second stage 2010, the GUI 100 displays a menu 2060 that includesa user selectable “Compose Clips” option along with other userselectable options (not shown). The “Compose Clips” option invokes thecreation of a sequence with selected media clips (the media clips 170and 2055 in this example). Similar to the menu 180 described above, themenu 2060 of different embodiments may include different numbers ofdifferent user selectable options for performing different functions. Auser can invoke the menu 2060 of some embodiments by selecting the“Edit” option in the menu bar 150 through a click operation (e.g., acursor click operation, a touch click operation, etc.). Otherembodiments provide other ways to invoke the menu 2060. For example,some such embodiments enable the user to invoke the menu 2060 using ahotkey, a keystroke, a series of keystrokes, a combination ofkeystrokes, or any other method to invoke a menu. The second stage 2010illustrates the selection of the “Compose Clips” option through a clickoperation using the cursor 2060.

The third stage 2015 shows the GUI 100 after the creation of a mediaclip sequence 2065. Since the media clips 170 and 2055 were selectedwhen the user invoked the sequence creation operation, the media clipsequence 2065 includes these two media clips. Different embodimentsspecify the order of the media clips in the sequence differently. Forinstance, some embodiments determine the order based on the position ofthe media clips in the media library, such as left to right, right toleft, top to bottom, bottom to top, etc. Some embodiments determine theorder within the sequence based on the order in which the media clipsare selected. In this example, the media editing application determinesthe order of the media clips in the media clip sequence 2065 based ontheir positions in the media library 145 on a left to right basis. Sincethe media clip 170 is positioned left of the media clip 2055 in medialibrary 145, the media clip 2055 comes after the media clip 170 in themedia clip sequence 2065.

The fourth through sixth stages 2020-2030 illustrate the creation of anaudition set 2070 in a similar manner as the creation of the auditionset 630 described above by reference to FIG. 6. In these stages2020-2030, a user selects and drags the media clip sequence 2065 ontothe media clip 175 in the composite display area 135 and subsequentlyselects the “Create Stack” option in the menu 625 that automaticallypops up in order to create audition set 2070. In this example, the mediaediting application sets media clip 175 as the active pick of theaudition set 2070 as it is the clip located in the composite displayarea 135.

The seventh through ninth stages 2035-2045 illustrated in FIG. 20B showthe display of the selection area 192 after its invocation throughselectable item 190 and scrolling through media clips of the auditionset 2070 in a similar fashion as described above by reference to thestages 115-130 of FIG. 1. These stages 2035-2045 illustrate the mediaclips that are part of the audition set 2070. Specifically, the eighthstage 2040 shows the media clip 175, which is the active pick, and theninth stage 2045 shows the media clip sequence 2065. As shown, the mediaediting application displays an expanded view of the media clip sequencein some embodiments that includes thumbnail representations for themedia clips that make up the sequence. When the sequence is too large(i.e., has too many clips), some embodiments only display a portion ofthe media clips that make up the sequence, or shrink the size of thethumbnails used to represent the media clips in the sequence.

FIGS. 21 and 22 illustrate an alternative method to create a sequenceand create an audition set that includes the sequence through the GUI100 according to some embodiments of the invention. As shown, thesefigures illustrate the GUI 100 at nine different stages 2105-2145 thatshow the creation of a sequence of media clips in the composite displayarea 135 and the creation of an audition set that includes the createdsequence.

Similar to the first stage of FIG. 20A, the first stage 2105 of the GUI100 illustrates a selection of several media clips (specifically, mediaclips 2155 and 175) through a selection box operation using the cursor160. However, in this example, the selected media clips are located inthe central compositing lane 155 of composite display area 135.

At the second stage 2110, the GUI 100 displays menu 2060 in the GUI 100.The user can invoke the display of the menu 2060 in the same or asimilar way to that described above by reference to stage 2010 of FIG.20A (i.e., through a cursor click operation, touchscreen clickoperation, etc.). This stage also illustrates the selection of the“Compose Clips” option through a click operation using the cursor 160.

The third stage 2115 illustrates the GUI 100 after the creation of mediaclip sequence 2160 from media clips 2155 and 175. In this example, mediaediting application determines the order of the media clips 2155 and 175in the media clip sequence 2160 by their chronological order in thetimeline of the composite display area 135. Thus, the media clip 175follows the media clip 2155 in the media clip sequence 2160.

As described above, the media editing application represents media clipsin the composite display area 135 using a timeline view. Since the mediaclip sequence 2160 includes the media clip 2155 and the media clip 175,the duration of the sequence 2160 is the combined duration of these twomedia clips. Accordingly, the horizontal length of the media clipsequence 2160 displayed in the composite display area 135 equals thecombined horizontal length of media clips 2155 and 175 as previouslydisplayed in the composite display area 135.

The fourth through sixth stages 2120-2130 of the GUI 100 illustrate thecreation of an audition set 2165 in a manner similar to the creation ofthe audition set 630 described above by reference to FIG. 6. In thestages 2120-2130, the user creates the audition set 2165 by selectingand dragging the media clip 170 onto the media clip sequence 2160 (e.g.,with a drag-and-drop operation) and then selecting the “Create Stack”option in the menu 625. In this example, the media editing applicationsets media clip sequence 2160 as the active pick of the audition set2165 as it is the media clip in the composite display area 135.

The seventh through ninth stages 2135-2145 illustrated in FIG. 22 showthe display of the selection area 192 after its invocation throughselectable item 190 and scrolling through media clips of the auditionset 2165 in a similar manner as described above by reference to thestages 115-130 of FIG. 1. In short, these stages 2135-2145 illustratethe media clips that are part of the audition set 2165. In particular,the eighth stage 2040 shows the media clip sequence 2160, which is theactive pick, and the ninth stage 2045 shows the media clip 170.

Although FIGS. 21 and 22 show a sequence in the composite display area135 displayed as a single graphical representation of the sequence, someembodiments display each media clip in the sequence when the sequence isdisplayed in the composite display area 135.

As described above, several embodiments allow a user to create asequence of video clips in the media library 145 and then create anaudition set using this sequence in the composite display area 135. Someembodiments further allow the addition of such a sequence to thecomposite display area without adding it to an audition set.Specifically, the media editing application of some embodiments allows auser to create a sequence of video clips in the media library 145 in anyone of the manners described above by reference to stages 2005-2015 ofFIG. 20A.

The media editing application then allows a user to add the sequencecreated in the media library to the composite display area, e.g.,through a menu command (e.g., a pop-up or pull-down menu command),through a drag operation, through a hot key command, etc. FIG. 23illustrates an example of adding a sequence 2350 that is created in themedia library to the composite display area through a drag operation.This example is illustrated in terms of four stages 2305-2320, which arefurther explained below.

In the example illustrated in FIG. 23, the sequence 2350 is created inthe media library by compositing three media clips, which are mediaclips G, H, and I in this example. The first stage 2305 shows thesequence 2350 being dragged from the media library 145 to the compositedisplay area 135. When the composite display area 135 receives thedragged sequence, the composite display area adds it to the graphicalrepresentation of the composite presentation that it is displaying. FIG.23 shows that different embodiments add the composed sequencedifferently to the composite display area.

Specifically, stage 2310 of this figure shows that some embodiments addthe sequence by unfolding the sequence into its constituting individualmedia clips G, H and I, and then adding the individual clips to thecomposite display area 135. Stages 2315 and 2320 show an alternative wayof adding the sequence to the composite display area. In particular,stage 2315 shows that some embodiments add the sequence by adding asequence clip representation 2355 to the composite display area. Stage2320 then illustrates that some embodiments allow an editor to open thesequence clip representation to examine and edit the constitutingindividual clips G, H, and I.

FIGS. 20-22 illustrate examples of audition sets that each include avideo clip and a sequence of video clips. However, as mentioned above,an audition set of some embodiments can include a variety of differenttypes of media clips. FIGS. 24 and 25 illustrate the creation of such anaudition set through the GUI 800. These figures illustrate the GUI 800at eleven different stages 2405-2455 that show the addition of differenttypes of media clips to the audition set 2070.

At the first stage 2405, the audition set 2070 is displayed in thecomposite display area 135 and an audio clip 2457 is displayed in themedia library 145. The second and third stages 2410 and 2415 illustratethe addition of media clip 2457 to the audition set 2070. The user addsmedia clip 2457 to the audition set 2070 in a similar manner asdescribed above by reference to stages 1105 and 1110 of FIG. 11, bydragging the clip to the audition set in the composite display area andselecting an “Add to Stack” option from a menu that automaticallyappears.

The fourth and fifth stages 2420 and 2425 illustrate the addition of aneffect clip to the audition set 2070. As with the media clip 2457, theuser adds the media clip 2460 to the audition set 2070 by dragging theeffect to the audition set in the composite display area and selectingthe “Add to Stack” option from the menu that automatically appears, asdescribed above by reference to the stage 1105 and 1110.

The sixth stage 2430 illustrates the GUI 800 after the addition of themedia clips 2457 and 2460 to the audition set 2070. At this stage, theaudition set 2070 includes four media clips: the media clip 175, themedia clip sequence 2065, and media clip 2457, and the media clip 2460.While the GUI 800 has the same appearance as at stage 2405, the mediaediting application has modified the data structure for audition set2070 to include the additional media clips.

The seventh through eleventh stages 2435-2455 illustrated in FIG. 25show the display of the selection area 192 after its invocation throughselectable item 190 and scrolling through media clips of the auditionset 2070 in a similar fashion as described above by reference to thestages 115-130 of FIG. 1. These stages 2435-2455 illustrate the mediaclips that are part of the audition set 2070. Specifically, the eighthstage 2440 shows the video clip 175, which is the active pick, the ninthstage 2445 shows the media clip sequence 2065, the tenth stage 2450shows the audio clip 2457, and the eleventh stage 2455 shows the mediaclip 2460. As shown, the media editing application displays the samewaveform for audio clip 2457 as used in the thumbnail representation ofthe audio clip in some embodiments. For the effects clip 2460, someembodiments simply use the name of the effect, as shown.

E. Creation of Audition Set in Media Library

Many of the examples described above illustrate the creation of anaudition set in the composite display area of the GUI of someembodiments. However, some embodiments allow the user to create auditionsets in other areas of the GUI (e.g., in the media library). Forinstance, the user may wish to organize media clips in the media librarythat are similar and/or that are intended to be different shots of aparticular scene in a movie without having to add any of the media clipsto the composite display area. In this manner, the user can createaudition sets of media clips that the user would like to associatetogether even though the user does not know where to place the auditionset in the composite display area. Thus, the user can add the auditionset to the composite display area at a later time.

FIGS. 26 and 27 illustrate examples of the creation of audition sets inthe media library 145 of GUI 100. Specifically, these figures eachillustrate a duplication operation performed on a portion of aparticular media clip in the media library 145 and an audition setcreation operation performed to logically group the particular mediaclip with the newly created media clip.

FIG. 26 conceptually illustrates the creation of an audition set in themedia library 145 of the GUI 100 of some embodiments. In particular,this figure illustrates the GUI 100 at six different stage 2605-2630that show an edit operation to create a new media clip and audition setcreation operation. The first stage 2605 of the GUI 100 illustrates theuser selecting a portion 2645 of the media clip 2635 by drawing aselection box 2640 using the cursor 160.

The second stage 2610 shows the GUI 100 with the portion 2645 of themedia clip 2635. As shown, the media editing application indicates theselected portion 2645 with a bold rectangle in this example. Theselected portion 2645 of the media clip 2635 represents a correspondingduration of the media content represented by the media clip. Inparticular, the selected portion 2645 represents approximately the firsthalf of the media content represented by the media clip 2635 sinceapproximately the left half of the thumbnail representation of the mediaclip 2635 is selected. Different embodiments may define the selectedportion 2645 of the media clip 2635 differently.

The second stage 2610 also illustrates the selection and movement of theportion 2645 (e.g., through a drag-and-drop operation) to an area in themedia library 145 not presently occupied by a media clip. In thisexample, the selection and dragging of the portion 2645 to an unoccupiedarea causes a new media clip 2650 to be generated and its representationdisplayed at the empty area of the media library 145. The media clip2650 represents the portion of the media content defined by the selectedportion 2645 (i.e., the media clip 2650 has the same in point as themedia clip 2635 but a different, earlier out point).

The third stage 2615 of the GUI 100 illustrates the display of a newmedia clip 2650 in the media library 145. This stage also shows theselection of the media clip 2650 through a click operation using thecursor 160. When the user selects media clip 2650, the media editingapplication displays the thumbnail image that represents the media clip2650 in the preview display area 140. In some embodiments, however, thepreview display area 140 remains unchanged with the selection of a mediaclip in the media library.

The fourth stage 2620 of the GUI 100 illustrates a selection of a secondmedia clip 2635 in the media library 145 through a click operation usingthe cursor 160, similar to the selection of the media clip 2650 in thethird stage 2615. The click operation used is such that media clip 2650also remains selected (e.g., a holding down a key while clicking acursor controller, touching both thumbnails at the same time on atouchscreen, etc.)

At the fifth stage 2625 of the GUI 100, the user invokes the creation ofan audition set. The user invokes the menu 180 with the user selectable“Create Stack” option displayed. As previously described above,selection of the “Create Stack” option creates an audition set thatrepresents a logical grouping of selected media clips (the media clips2635 and 2650 in this example).

The sixth stage 2630 illustrates the GUI 100 after the creation of anaudition set 2655. As shown, the media clips 2635 and 2650 are no longerdisplayed as individual media clips. Instead, the GUI displays a stackof clips at the previous location of clip 2635. Furthermore, on the topthumbnail of this stack, the GUI displays a user selectable UI item 2660to indicate that the stack is an audition set. In some embodiments, theuser selectable UI item 2660 can be used to open and close a selectionarea similar to that invoked with the user selectable UI item 190described above. Some embodiments also display a label that indicates anumber of media clips in the audition set.

While FIG. 26 illustrates the media clips of the audition set 2655stacked on top of one another in an offset manner, some embodiments maydisplay audition sets differently in the media library. For instance,some embodiments display an audition set as a single thumbnailrepresentation without any offset stacking, using an indicator such asitem 2660 to indicate to the user that the thumbnail represents anaudition set.

FIG. 26 illustrates a creation of the audition set 2655 in the medialibrary 145 by selecting media clips in the media library 145 andselecting an option from a pull-down menu. Some embodiments provideother ways of invoking the audition set creation operation, such asusing a hotkey, a keystroke, a series of keystrokes, a combination ofkeystrokes, or any other appropriate method for invoking a command.

FIG. 27 illustrates another example of the creation of an audition setin the media library 145 of the GUI 100. FIG. 27 illustrates the GUI 100at four different stages 2705-2720 that show an edit operation andaudition set creation operation of some embodiments. The first andsecond stages 2705 and 2710 are the same as the first and second stages2605 and 2610 of FIG. 26, in which the user creates a new media clipfrom a portion of an existing media clip.

The third stage 2715 of the GUI 100 shows the performance of an auditionset creation operation. At this stage the user selects and drags themedia clip 2650 (e.g., through a drag-and-drop operation) using thecursor 160 towards the media clip 2635 in the media library 145.

The fourth stage 2720 illustrates the GUI 100 after the placement of themedia clip 2650 on top of the media clip 2635 to create an audition set2655. The end result of the GUI 100 is the same as that of stage 2630 ofFIG. 26, in that the clips are shown as a stack with an indicator UIitem 2660 to indicate the new audition set, and an audition set datastructure has been created.

While the examples illustrated in FIGS. 26-27 show only two media clipsselected to create an audition set, multiple media clips can be selectedand subsequently grouped as an audition set in some embodiments. In somesuch embodiments, multiple media clips can be selected by holding akeyboard key and performing click operations on each media clip the userwishes to select, or by using the cursor 160 to perform a selection boxselection operation. Other embodiments may use other methods forselecting GUI items in the GUI 100 as well, such as touchscreenoperations.

As described above, FIGS. 26 and 27 show several examples of thecreation of an audition set in the media library 145. Once an auditionset has been created in the media library, a user can add the auditionset to the composite presentation in the composite display area. FIG. 28illustrates adding an audition set to a composite presentation throughthe GUI 100 according to some embodiments of the invention. This figureillustrates the GUI 100 at four different stages 2805-2820 that show theaddition of the audition set 2655 to a composite presentation displayedin the composite display area 135.

The first stage 2805 continues from the last stage 2630 of FIG. 26. Asshown, this stage illustrates the selection of the audition set 2655through a click operation using the cursor 160. The GUI 100 indicatesthe selection of the audition set 2655 by bolding the audition set 2655.

At the second stage 2810, the GUI 100 displays a menu 2825 that includesa user selectable “Append to Timeline” option and other options (notshown). The “Append to Timeline” option appends a selected media clip(the active pick of the audition set 2655 in this example) to the end ofthe composite presentation. Some embodiments allow the user to invokethe menu 2825 by selecting the “Stacks” option in the menu bar 150through a click operation (e.g., a cursor click operation, a touch clickoperation, etc.). Other embodiments provide other ways to invoke themenu 2825. For example, some such embodiments allow the user to invokethe menu 2825 using a hotkey, a keystroke, a series of keystrokes, acombination of keystrokes, or any other method to invoke a menu. Thesecond stage 2810 illustrates the selection of the “Append to Timeline”option through a click operation using the cursor 160.

The third stage 2815 of the GUI 100 conceptually shows the addition ofthe audition set 2655 (i.e., the active pick of the audition set 2655)to the composite presentation displayed in the composite display area135. Some embodiments actually display the addition of the audition setor media clip (e.g., an animation of the audition set 2655 moving fromthe media library 145 to the composite display area 135) upon theselection of the “Append to Timeline” option.

The fourth stage 2820 illustrates the GUI 100 after the addition of theactive pick of the audition set 2655 to the composite presentation. Thecomposite display area 135 now displays an audition set 2835, which isthe timeline view of the audition set 2655, at the end of the compositepresentation after “Clip D.” As shown, a user selectable UI item 190 isdisplayed in the audition set 2835 to visually indicate that it is anaudition set. Some embodiments automatically append the media clip oraudition set to the end of the composite presentation upon selection ofthe “Append to Timeline” option. In some embodiments, however, aplayhead or other UI item may be used to specify a location in thetimeline at which to add the clip or audition set.

FIG. 29 also illustrates the addition of an audition set to a compositepresentation using the GUI 100 according to some embodiments of theinvention. Rather than adding an audition set to the end of thecomposite presentation, some embodiments allow the user to add theaudition set to any location in the composite presentation. FIG. 29illustrates the GUI 100 at four different stages 2905-2920 that show theaddition of the audition set 2655 to a particular location in thecomposite presentation using an anchor lane of the composite displayarea.

The first stage 2905 is the same as the first stage 2805, in which theuser selects the audition set 2655. The second stage 2910 shows the userdragging audition set 2655 (e.g., through a drag-and-drop operation)from the media library 145 into the composite display area 135. Asshown, when the user drags the audition set 2655, a timeline viewrepresentation of the active pick is displayed in the timeline view(i.e., a rectangle with a duration determined by the length of theactive pick) to assist the user in placing the audition set 2655 in thecomposite display area 135. Some embodiments display the audition set2655 in the audition set 2655's thumbnail view until the thumbnail iswithin a threshold distance of the composite display area 135. When theuser drags the audition set 2655 within the threshold distance, theediting application displays the timeline view.

At the third stage 2915, the GUI 100 illustrates the anchoring of theaudition set 2655 to the media clip 175. In some embodiments, when theuser brings the representation of the audition set within a thresholddistance of the media clip in the composite display area, the auditionset 2655 automatically “snaps” to the media clip. With the audition setanchored to the media clip in the composite display area, the user canadjust the position of the audition set by moving it left and right insome embodiments.

The fourth stage 2920 shows the result of the operation to add theaudition set to the composite display area. After the user has finisheddragging the audition set 2655 into the composite display area 135, themedia editing application adds the active pick of the audition set 2655to the composite presentation at the location shown in the compositedisplay area 135. In some embodiments, this entails modifying a projectdata file to indicate the inclusion of a particular media clip at aparticular time.

II. Previewing an Audition Set

As described above, each of the media clips in an audition set is acandidate for inclusion at a particular location in a composite displayarea. When the user includes an audition set in the compositepresentation, some embodiments only treat one of the video clips as acommitted media clip in the composite presentation at any given time.The following section describes various tools of some embodiments thatallow the user to examine and evaluate the media clips in an auditionset (or single media clips not in an audition set) at a particularlocation in the composite presentation. For instance, the media editingapplication of some embodiments allows the user to browse media clips,skim media clips, and preview media clips, among other functionalities.

Many of the examples above show the selection area 192 positioned at aparticular location within a GUI (e.g., just above the centralcompositing lane 155 of the composite display area 135). Someembodiments provide functionality that enables a user to position theselection area 192 at different locations in a GUI. For instance, whenthe user wishes to preview a portion or all of a composite presentationin the preview display area 140, the user may want to move the selectionarea 192 so that it does not obstruct the preview display area 140.

FIG. 30 illustrates the movement of the selection area 192 within theGUI 100 according to some embodiments of the invention. Particularly,FIG. 30 illustrates the GUI 100 at five different stages 3005-3025 thatshow several example movements of the selection area 192.

At the first stage 3005, the GUI 100 displays the audition set 185 inthe composite display area 135 and the selection area 192. In thisexample, the user has selected the selectable UI item 190 (e.g., througha cursor click operation using the cursor 160 or a touch operation witha touchscreen device) to invoke the display of the selection area 192.

The second stage 3010 of the GUI 100 illustrates the start of a movementof the selection area 192 to a new location in the GUI 100. In thisexample, the user moves the selection area 192 by performing aclick-and-drag operation using the cursor 160 (or through a touchoperation using a touchscreen device) on any region in the selectionarea not occupied by a media clip or the scroll bar 194. As shown by thelarge arrow, the user is in the process of moving the cursor 160 to theleft after selecting the selection area 192 at the present location ofthe cursor 160.

The third stage 3015 illustrates the selection area 192 moved to theleft of its previous position. At this stage, the user may havecompleted the click-and-drag operation (e.g., by releasing a cursorclick operation or removing a finger from a touchscreen), or may stillbe in the middle of the click and drag operation.

The fourth and fifth stages 3020 and 3025 illustrate another movement ofthe selection area 192 in the GUI 100. Specifically, the user moves theselection area 192 up from its position in the third stage 3015 in asimilar manner to that used to move the selection area 192 in the secondand third stages 3010 and 3015. As shown in the fifth stage 3025, theGUI 100 now displays the selection area 192 in its upper left corner.

While FIG. 30 describes one method for moving the selection area 192 inthe GUI 100, other embodiments may provide other ways to move theselection area 192. For example, some embodiments allow the user toenable and disable (e.g., toggle) a positioning mode (e.g., by using ahotkey, keystroke, combination of keystrokes, or selection from a pop-upor pull-down menu, etc.). When the positioning mode is enabled, the usercan move the selection area 192 by using keystrokes, such as arrow keyinputs. Once the user has moved the selection area 192 to a desiredlocation, the user can disable the positioning mode (e.g., by using asimilar hotkey, keystroke, combination of keystrokes, or selection froma pop-up or pull-down menu, etc.) to set the position of the selectionarea 192 at its desired location.

FIG. 30 illustrates the movement of the selection area 192 withinperimeter of the GUI 100. However, some embodiments allow the user tomove some or all of the selection area beyond the perimeter of the GUI.As mentioned above, the user may wish to move the selection area when itobstructs an area of the GUI that the user desires to view.Additionally, some embodiments provide other techniques for modifyingthe display of the selection area, such as resizing the area.

A. Selecting an Active Pick for an Audition Set

In some embodiments, the user can change the active pick of an auditionset by selecting another media clip in the audition set to replace thecurrent active pick (e.g., through the selection area). A user may wishto change the active pick of an audition set for different reasons. Forexample, several media clips within an audition set may be differenttakes of one particular shot of a movie. By allowing the user to createan audition set that includes these several media clips, the user canexamine the different takes and select the one the user wants to use inthe movie. The auditioning feature then allows the user to select adifferent take from the audition set at any time in case the userchanges his mind.

FIG. 31 illustrates changing the active pick for an audition set usingthe GUI 100 of some embodiments. In particular, this figure illustratesthe GUI 100 at six different stages 3105-3130 of the active pickselection operation. For this example, the GUI 100 continues from thelast stage 620 illustrated in FIG. 6, at which an audition set 630 iscreated. At the first stage 3105 of the GUI 100, the user selects theselectable audition set indicator UI item 190 through a click operationusing the cursor 160, as shown by a change in the appearance of the userselectable UI item 190.

The second stage 3110 illustrates the GUI 100 after the selection of theuser selectable UI item 190. As shown, the GUI 100 displays (i.e.,opens) the selection area 192 (that includes the scroll bar 194). Theselection area 192 displays the two media clips of the selected auditionset, clips 165 and 175. The graphical representation of media clip 175includes an active pick indicator 196 to indicate that it is presentlythe active pick of the audition set 630.

In some embodiments, the media editing application automaticallydisplays the selection area 192 in the GUI 100 upon receiving aselection of the user selectable UI item 190 (e.g., through theillustrated cursor click operation, a touch click operation, etc.). Someembodiments provide other mechanisms for invoking the display of theselection area 192. For example, some of these embodiments allow theuser to invoke the selection area 192 using a hotkey, a keystroke, aseries of keystrokes, a combination of keystrokes, an option selectedfrom a pop-up or pull-down menu, a different touch operation for atouchscreen device, or any other appropriate method to invoke thedisplay of the selection area 192. Some embodiments animate the openingof the selection area (e.g., by showing the selection area opening outof the selected media clip representation.

At the third stage 3115, the user is in the process of scrolling throughmedia clips 165 and 175 in the selection area 192. In particular, thisstage shows the selection of the right arrow of the scroll bar 194 bythe user through a click operation using the cursor 160, as shown by achange in the appearance of the right arrow. The user is scrollingthrough the media clips 165 and 175 from right to left, as indicated bythe arrow over clip 175 pointing to the left, and the indicator in thescroll bar 194 is also changing positions accordingly. As shown in thisstage, some embodiments animate the movement of the media clips throughthe center of the selection area, as in this case the size of therepresentation of media clip 175 is decreasing while the size of therepresentation of media clip 165 increases. Although this exampleillustrates the use of the arrows of the scroll bar 194 to scrollthrough the media clips displayed in the selection area 192, in someembodiments the user may also use the indicator of the scroll bar 194 toscroll through the media clips displayed in the selection area 192, aspreviously mentioned above.

The fourth stage 3120 of the GUI 100 illustrates the selection area 192with media clip 165 now centered in the display. At this stage, the userselects the media clip 165 as the active pick of the audition set 630through a click operation (e.g., single-click, double-click, etc.) usingthe cursor 160.

The fifth stage 3125 of the GUI 100 illustrates the selection area 192after the user has selected the media clip 165 as the active pick of theaudition set 630 (e.g., by the cursor click operation described above, atouchscreen operation such as a single or double tap of the media cliprepresentation, etc.). As shown, the media editing application nowdisplays indicator 196 on the media clip 165 instead of on the mediaclip 175 to indicate the new active pick selection. In some embodiments,the media editing application also modifies a data structure for theaudition set 630 to refer to media clip 165 as the active pick for theset.

The sixth stage 3130 illustrates the GUI 100 no longer displaying theselection area 192. In this case, the user has selected the userselectable UI item 190 in order to close the selection area 192 (e.g.,with a cursor click operation, a touch click operation, etc.). Otherembodiments allow the user to close the selection area differently—e.g.,through a hotkey, a keystroke, a series of keystrokes, a combination ofkeystrokes, an option selected from a pop-up or pull-down menu,selection of a “close window” item displayed within the selection area,etc.

The stages 3105-3130 of FIG. 31 illustrate an active pick selectionoperation performed by scrolling through the media clips of an auditionset displayed in the selection area 192 and selecting one of the mediaclips as the active pick of the audition set. Some embodiments enablethe user to perform a scroll and selection operation. For instance, somesuch embodiments allow the user to use a hotkey, a keystroke (e.g.,right arrow, left arrow), a series of keystrokes, a combination ofkeystrokes (e.g., command-shift-right arrow, command-shift-left arrow),an option selected from a pop-up or pull-down menu, a touch operationfor a touchscreen device, or other methods to simultaneously scroll inone direction and select the next media clip in such direction as theactive pick of the audition set 630.

FIG. 31 illustrates an exemplary series of operations for selecting anactive pick for the audition set 630. However, one of ordinary skill inthe art will recognize that a user can use many different types ofoperations to select an active pick for an audition set. For example,the user can scroll through the media clips displayed in the select areaany number of times before selecting a media clip to be the active pickof the audition set. Some embodiments allow the user to select (e.g., byclicking with a cursor or touching on a touchscreen) a media cliprepresentation that is not centered in the selection area in order toselect the media clip as an active pick. Some embodiments allow the userto select an active pick without opening the selection area. Forinstance, a user might be able to select an audition set and then use akeystroke or key combination to cycle through the media clips as activepicks for the audition set.

As previously noted above, the characteristics and attributes of anactive pick of an audition set are used when the audition set interactswith the media editing application (e.g., when the media editingapplication renders the composite presentation of which the audition setis a part). As different media clips have different durations, the sizeof the representation of the audition set in the display area may bedifferent with different media clips selected as the active pick for theset.

FIG. 32 illustrates an example of the display of such differently-sizedgraphical representations when the active pick of an audition setchanges. Specifically, FIG. 32 illustrates the GUI 100 at six differentstages 3205-3230 that show the selection of a new active pick for anaudition set. The first stage 3205 is the same as the first stage 3105of FIG. 31. That is, this stage of the GUI 100 continues from the laststage 620 illustrated in FIG. 6 and shows the selection of the userselectable UI item 190 through a click operation using the cursor 160.

The second stage 3210 is similar to the second stage 3110 of FIG. 31except the selection area 192 displays a label specifying the name andduration of the media clip displayed at or near the center of theselection area 192. As shown, the media clip 175 is named “Clip D” andhas a duration of one minute. The indicator 196 is also displayed on themedia clip 175 to indicate that it is the active pick of the auditionset 630. Since the media clip 175 is the active pick, the media editingapplication uses the duration of the media clip 175 to determine thehorizontal length 3240 of the audition set 630 in the composite displayarea 135. In other words, the horizontal length 3240 of the audition set630 represents a duration of one minute in the composite display area135.

The third stage 3215 is the same as the third stage 3115 illustrated inFIG. 31, which shows the user scrolling through the media clips 165 and175 in the selection area 192. The fourth stage 3220 of the GUI 100 issimilar to the fourth stage 3120 of FIG. 31 except that the selectionarea 192 displays the name and duration of the media clip 165, which isdisplayed at or near the middle of the selection area 192. As shown,media clip 165 is named “Clip E” and has a duration of two minutes. Atthis stage, the user selects the media clip 165 as the active pick ofthe audition set 630 through a click operation (e.g., single-click,double-click, etc.) using the cursor 160.

The fifth stage 3225 is similar to the fifth stage 3125 shown in FIG. 31in that this stage illustrates the selection area 192 after the user hasselected the media clip 165 as the active pick of the audition set 630(e.g., by the cursor click operation described above, a touchscreenoperation such as a single or double tap of the media cliprepresentation, etc.). As shown, the media editing application nowdisplays indicator 196 on the media clip 165 instead of on the mediaclip 175 to indicate the new active pick selection. In some embodiments,the media editing application also modifies a data structure for theaudition set 630 to refer to media clip 165 as the active pick for theset. In addition, the GUI now displays the audition set 630 with a newhorizontal length 3250 in the composite display area 135. As theduration of media clip 165 is twice that of media clip 175, the lengthof the audition set's representation in the composite display area hasdoubled.

The sixth stage 3230 is the same as the sixth stage 3130 of FIG. 31.This stage illustrates that the GUI no longer displays the selectionarea 192, as a result of the user selecting the user selectable UI item190 (e.g., with a cursor click operation, a touch click operation,etc.).

B. Skimming a Media Clip in an Audition Set

In addition to the ability to select an active pick within the selectionarea, some embodiments provide the user with the ability to skim throughmedia clips displayed in the selection area. Skimming, in someembodiments, involves dragging a playhead through the representation ofa video clip so as to view different images (i.e., frames or fields) ofthe video clip. FIG. 33 illustrates a user skimming a media clip of theaudition set 630 through the GUI 100 according to some embodiments ofthe invention. In particular, this figure illustrates the GUI 100 atfive different stages 3305-3325 of an example skimming operation.

In this example, the first stage 3305 continues after the last stage 620of FIG. 6, in which the audition set 630 was created. At the first stage3305 of the GUI 100, the GUI displays the selection area 192, which hasbeen invoked through a selection (e.g., a cursor click operation, touchclick operation, etc.) of the user selectable UI item 190, as describedabove by reference to FIG. 1. As shown, the selection area 192 displaysthe media clips 165 and 175. The selection area indicator 196 and aplayhead 3330 (also referred to as a scrubber bar) are displayed overthe representation of the media clip 175.

The horizontal position of the playhead 3330 along the media clip 175indicates the chronological position within the media content of mediaclip 175 of the image presently displayed (e.g., skimmed). As describedabove, the media content of a media clip is defined by in and out pointsin a source media file in some embodiments. In this example, theplayhead 3330 positioned along the left side of the media clip 175indicates that the first image in the video clip 175 is presentlydisplayed in the thumbnail representation of the clip. Some embodiments,on the other hand, skim through a media clip from right to left (i.e.,the playhead at the right edge indicates the beginning of the clip).Some embodiments display the playhead for the user to use in theskimming operation whenever a video clip is displayed in the center ofthe selection area, while other embodiments only display the playhead inresponse to user input (e.g., a hotkey or combination of keystrokes, theuser performing a click-and-drag operation over the displayed cliprepresentation, etc.).

The second stage 3310 of the GUI 100 illustrates the user beginning toskim through the media clip 175. As shown, the user moves the playhead3330 across the media clip 175 using the cursor 160 (e.g., by performinga click-and-drag operation on the playhead 3330 or otherwise moving thecursor over the representation of the media clip 175). Since theplayhead 3330 is positioned near the left side of media cliprepresentation 175, the media clip representation 175 displays an imagefrom near the beginning of its media content. This image is similar tothe image displayed in the first stage 3305 (e.g., the first frame ofthe media content) except that the scene of the golfer and the golf ballrolling towards the hole is zoomed in slightly and the golf ball iscloser to the hole.

The third through fifth stages 3315-3325 illustrate the user continuingto skim through the media clip 175 using the cursor 160. At stage 3315,the playhead 3330 is positioned about one third of the way from the leftside of the media clip 175. At stage 3320, the playhead is positionedabout four fifths of the way across the media clip representation 175,and at stage 3325 the playhead has nearly reached the right edge of themedia clip representation 175. These stages show that the video clipprogresses as the user skims through, with the images being furtherzoomed in and the golf ball closer to the hole at each subsequent stage.

While FIG. 33 shows the user skimming through the media clip 175 fromthe start to the end of the media, one of ordinary skill will realizethat the user need not skim through a media clip monotonically. That is,the user can skim back and forth through the clip (e.g., to replay aportion of the clip multiple times).

C. Previewing a Media Clip in an Audition Set

As mentioned above, the media editing application of some embodimentsenables the user to preview a media clip in an audition set. That is,within the thumbnail representation of the media clip shown in theselection area, the media editing application plays the content of themedia clip. The following figures illustrate examples of such apreviewing feature provided by some embodiments. In particular, FIG. 34illustrates an example of a manual previewing feature and FIGS. 35-37illustrate several examples of an automatic previewing feature.

As stated, FIG. 34 illustrates the manual preview of a media clip in anaudition set according to some embodiments of the invention. This figureillustrates the GUI 100 at six different stages 3405-3430 that show apreview of a media clip of the audition set 630 in the selection area192.

The first three stages 3405-3415 are the same as the first three stages3105-3115, respectively, as illustrated in FIG. 31. These stages show aselection of the user selectable UI item 190 to invoke the display ofthe selection area 192 and the user scrolling through the media clips toplace the media clip 165 in the selection area 192. With the media clip165 located in the center of the selection area 192, the user of themedia editing application selects the media clip (e.g., through a clickoperation such as a cursor click or a touch click). In this example, themedia content of the media clip 165 is a video of a golf ball rollingtowards a hole after a golfer has hit the golf ball.

At the fourth stage 3420, the GUI 100 displays a menu 3435 that includesa user selectable “Preview” option and other user selectable options(not shown). Selection of the “Preview” option invokes a preview of aselected media clip in the selection area 192 (the media clip 165 inthis example). Some embodiments automatically display the menu 3435 whenthe user selects a media clip in the selection area 192 in a particularmanner (e.g., through a particular option such as a right click orspecific touchscreen operation). However, some embodiments provide otherways to invoke the menu 3435. For instance, some such embodiments allowthe user to invoke the menu 3435 using a hotkey, a keystroke, a seriesof keystrokes, a combination of keystrokes, or any other appropriatemethod to invoke a menu. As shown, the fourth stage 3420 illustrates theselection of the “Preview” option through a click operation using thecursor 160. The media editing application starts previewing the mediaclip 165 shortly after the selection of the “Preview” option.

The fifth stage 3425 illustrates the GUI 100 as the media editingapplication previews the media clip 165 in the selection area 192. Asmentioned above, the horizontal position of the playhead 3330 along themedia clip 165 indicates the chronological position of the media contentof the media clip 165 presently displayed (i.e., how far in the durationof the media clip the presently displayed video frame is located). Themedia content of the media clip 165 displayed within the media clip 165shows the golf ball rolling closer to the hole.

The sixth stage 3430 illustrates the GUI 100 at a later time as thepreview of the media clip 165 is nearly complete. As such, the GUI 100now displays the playhead 3330 at a position closer to the right side ofthe media clip 165 than in the previous stage 3425. The frame of thevideo clip 165 displayed within the graphical representation of themedia clip shows the golf ball about the roll into the hole.

FIG. 34 illustrates the manual preview of a particular single media clipin an audition set. In addition, some embodiments provide a feature thatautomatically previews each of the media clips in an audition set inorder to allow the user to see how each of the media clips will appearin the composite presentation. The following FIGS. 35-37 conceptuallyillustrate different examples of such an automatic previewing feature.

FIG. 35 illustrates automatically previewing an audition set using theGUI 100 according to some embodiments of the invention. Specifically,this figure illustrates the GUI 100 at six different stages 3505-3530that show the automatic preview of the media clips in the audition set630.

In this example, the user previews two different candidate shots (themedia clip 165 and 175) of one scene for inclusion in the compositepresentation. Specifically, the media content of the media clip 175shows a golf ball rolling towards a hole, after a golfer has hit thegolf ball, with the camera gradually zooming in on the hole as the golfball rolls towards the hole. The media content of the media clip 165shows a similar scene except that the shot does not zoom in on the hole.

The first stage 3505, in this example, continues from the last stage 620shown in FIG. 6, at which the audition set 630 was created. This stageof the GUI 100 illustrates the selection of the audition set 630 througha click operation using the cursor 160, as indicated by the bolding ofthe border of the audition set 630.

At the second stage 3510, the GUI 100 displays a menu 3535 that includesa user selectable “Audition Stack” option along with other userselectable options (not shown). Selection of the “Audition Stack” optioninvokes the automatic previewing of the media clips in a selectedaudition set. Some embodiments display the menu 3535 when the userselects the “Stacks” option in the menu bar 150 through a clickoperation (e.g., a cursor click operation, a touch click operation,etc.). Some embodiments also provide other ways to invoke the menu 3535.For example, some such embodiments allow the user to invoke the menu3535 using a hotkey, a keystroke, a series of keystrokes, a combinationof keystrokes, or any other method to invoke a menu. As shown, thesecond stage 3510 also illustrates the user selecting the “AuditionStack” option through a click operation using the cursor 160. The mediaediting application automatically starts the previewing of the mediaclips of the audition set 630 shortly after the selection of the“Audition Stack” option.

The third stage 3515 illustrates the GUI 100 during the preview of themedia clip 175. As shown, the GUI 100 displays the selection area 192,which displays the media clips 165 and 175 of the audition set 630. Whenthe user selects the “Audition Stack” option, some embodimentsautomatically open the selection area to preview the different mediaclips in the selected audition set. At this stage, the playhead 3330 ispositioned approximately a third of the way through the media clip 175.As mentioned above, the horizontal position of the playhead 3330 alongthe media clip 175 indicates the chronological position in the mediaclip of the media content (e.g., video image) presently displayed. Theframe of media clip 175 presently displayed within the thumbnailrepresentation shows the scene mentioned above, with the camera zoomedin on hole and the golf ball rolling closer towards the hole.

The fourth stage 3520 illustrates the GUI 100 further along the previewof the media clip 175. At this stage the playhead 3330 is now positionedcloser to the right side of the media clip 175 than in the previousstage 3515. In addition, the video image displayed within therepresentation of media clip 175 shows the scene further zoomed in onthe hole with the golf ball closer to the hole. After completion of thepreview of the media clip 175, the media editing applicationautomatically starts the preview of the next media clip (the media clip165) in the selection area 192.

At the fifth stage 3525, the GUI 100 is now previewing the media clip165. Similar to media clip 175 in the previous stages, the playhead 3330is positioned on the media clip 165 to indicate the chronologicalposition in the media clip 165 of the presently displayed video image.As shown, the image displayed within the media clip 165 shows the golfball rolling towards the hole after the golfer has hit the golf ball. Inthis media clip, the camera does not zoom in on the golf ball.

The sixth stage 3530 illustrates the GUI 100 further along the previewof the media clip 165. At this stage the playhead 3330 is now positionedcloser to the right side of the media clip 165 than in the previousstage 3525. In addition, the video image displayed within therepresentation of media clip 165 shows the golf ball closer to the hole.As the audition set 630 only includes two media clips (clips 165 and175), after completing the preview of the second media clip the previewis complete. Some embodiments automatically close the selection areaafter completing the preview.

In the preview shown in FIG. 35, the media editing applicationillustrates each of the media clips of an audition set previewed once.Some embodiments terminate the automatic preview feature after each ofthe media clips have been previewed once, while other embodimentscontinue to cycle through and automatically preview the media clipsuntil an event occurs. Examples of such events include user input tostop the automatic previewing, a threshold number of cycles through theclips being reached, or a time limit being reached.

FIGS. 36 and 37 illustrate an example of a different automaticpreviewing feature of some embodiments that plays each clip in anaudition set with a pre-roll and post-roll. FIGS. 36 and 37 illustratethe GUI 100 at ten different stages 3605-3650 that show the automaticpreviewing of the media clips in the audition set 630 with the pre-rolland post-roll feature in the preview area of the GUI 100.

When previewing a media clip, some embodiments include a portion of thecomposite presentation immediately preceding the media clip (alsoreferred to as “pre-roll”) and immediately following the media clip(also referred to as “post-roll”). In this manner, the user can view thetransitions before and after the media clip to give context to the userwith which to evaluate each media clip in the audition set at thelocation in the composite presentation of the audition set. Someembodiments specify these portions in terms of an amount of time (e.g.,10 seconds, 20 second, 30 seconds, etc.) that may be defined by defaultor by the user through a preference settings option of the media editingapplication. As in FIG. 35, the user in this example previews twodifferent candidate shots (the media clips 165 and 175) of one scene forinclusion in the composite presentation.

Referring back to FIG. 36, the first stage 3605 shows the GUI 100 at astage similar to the stage 620, after the creation of the audition set630, except that the composite presentation displayed in the compositedisplay area 135 also includes a media clip 3655 placed after theaudition set 630. This stage illustrates the selection of the auditionset 630 through a click operation using the cursor 160.

At the second stage 3610, the GUI 100 displays a menu 3665 that includesa user selectable “Audition Stack” option along with other userselectable options (not shown). The menu 3665 is similar to the menu3535 except that the “Audition Stack” option invokes an automaticpreviewing of the media clips in the audition set 630 with the pre-rolland post-roll clip portions described above. In addition, unlike in FIG.35, the media editing application displays the preview in the previewdisplay area 140 as well as the selection area 192. As shown, the secondstage 3610 also illustrates the user selecting the “Audition Stack”option through a click operation using the cursor 160.

The third stage 3615 of the GUI 100 illustrates the display of thepre-roll for the preview of the media clip 175 in the audition set 630.In particular, the preview display area 140 displays the pre-roll (e.g.,an end portion of the media content of the media clip 3660), which showsthe golfer before hitting the golf ball towards the hole. The GUI 100also now displays the selection area 192. In some embodiments, as shown,the media editing application displays the selection area 192 shortlyafter the selection of the “Audition Stack” option.

As shown, the media editing application displays the playhead 3330 overthe representation of media clip 175 in the selection area 192. Asmentioned above, the horizontal position of the playhead 3330 along themedia clip 175 indicates the chronological position of the currentlydisplayed video image within the media clip 175. Because the currentvideo image is from the pre-roll rather than the media clip 175 itself,the playhead 3330 is positioned at the left side of the media clip 175and the first video image of the media clip 175 is displayed within theits thumbnail representation.

As mentioned above, some embodiments allow the user to move or resizethe selection area. In this example, the user has resized (i.e.,decreased the size) the selection area 192 so that it does not obstructthe preview display area 140. In some cases, the user might move theselection area rather than resizing it. Some embodiments, on the otherhand, do not display the selection area during the automatic previewingof the media clips in the audition set, or automatically modify the sizeor location of the selection area so that the preview display arearemains unobstructed.

In the fourth stage 3620, the preview of the pre-roll has finished andthe GUI 100 displays the preview of media clip 175. As shown, thepreview display area 140 displays a zoomed-in video image of the hole asthe golf ball rolls towards it. Since the preview now shows the mediacontent of the media clip 175, the media editing application displaysthe same video image within the thumbnail representation of the mediaclip 175 in the selection area 192. In addition, the position of theplayhead 3330 displayed on the media clip 175 corresponds to thechronological position of this video image in the media clip 175.

The fifth stage 3625 illustrates the GUI 100 further along the previewof the media clip 175. At this stage, the playhead 3330 is nowpositioned closer to the right side of the media clip 175 than in theprevious stage 3620. In addition, the video image displayed within therepresentation of media clip 175 shows the scene further zoomed in onthe hole with the golf ball closer to the hole.

At the sixth stage 3630, the GUI 100 now displays the post-roll for thepreview of the media clip 175, having completed the preview of the mediaclip itself. Thus, the preview display area 140 now displays a videoimage from the beginning portion of the media clip 3655, which shows thegolfer's reaction to the golf ball rolling into the hole. Similar toduring the preview of the pre-roll, the playhead 3330 is positioned atthe right side of the media clip 175 and the last frame of the mediaclip 175 is displayed within its thumbnail representation in selectionarea 192.

The seventh stage 3635 illustrated in FIG. 37 shows the GUI 100 afterthe media editing application has completed the post-roll for the mediaclip 175 and started the preview of the media clip 165. Because themedia clip 165 is a candidate for the same position in the compositepresentation as the media clip 175, at this stage the media editingapplication displays the same pre-roll as displayed for the media clip175. As such, the GUI 100 displays the same video image in previewdisplay area 140 as at stage 3615.

At the eighth stage 3640, the preview of the pre-roll has finished againand the GUI 100 displays the preview of media clip 165. As shown, thepreview display area 140 displays the golf ball rolling towards thehole. Since the preview now shows the media content of the media clip165, the media editing application displays the same video image withinthe thumbnail representation of the media clip 165 in the selection area192. In addition, the position of the playhead 3330 displayed on therepresentation of media clip 165 corresponds to the chronologicalposition of this video image in the media clip 165.

The ninth stage 3645 illustrates the GUI 100 further along the previewof the media clip 165. At this stage, the playhead 3330 is nowpositioned closer to the right side of the media clip 165 than in theprevious stage 3640. In addition, the video image displayed in thepreview display area 140 (and within the clip representation for mediaclip 165) shows the scene with the golf ball closer to the hole.

At the tenth stage 3650, the GUI 100 now displays the post-roll for thepreview of the media clip 165, having completed the preview of the mediaclip itself. Because the media clip 165 is a candidate for the sameposition in the composite presentation as the media clip 175, at thisstage the media editing application displays the same post-roll asdisplayed for the media clip 175. As such, the GUI 100 displays the samevideo image in preview display area 140 as at stage 3630.

FIGS. 36 and 37 illustrate automatically previewing media clips in anaudition set with the pre-roll and post-roll features and displaying thepreview in the preview display area 140. However, the automatic previewdoes not necessarily have to include all of these features. For example,some embodiments may display the preview in the preview display area 140but do not preview the pre-roll and post-roll. Other embodiments mayinclude different combinations of these features in implementing theautomatic previewing. Moreover, for the manual previewing of a mediaclip that was described above by reference to FIG. 34, some embodimentsutilize one or more of these features (e.g., the pre- and post-roll, thepreview display area, etc.).

The preceding figures illustrate several examples of previewing mediaclips in a selection area of some embodiments. FIG. 38 conceptuallyillustrates a process 3800 of some embodiments for previewing a mediaclip. As shown, the process 3800 begins by receiving (at 3805) input topreview a media clip. The input can be received from a selection of anoption from a pop-up menu in some embodiments, as illustrated in FIG.34. Some embodiments receive the input from a selection of an optionfrom pull-down menu, as shown in FIGS. 35 and 36. The selection inputmay be from a cursor controller (e.g., a click input), through atouchscreen (e.g., touching a menu option), from a keyboard, etc.

Next, the process 3800 identifies (at 3810) the primary media clip orclips to preview. The primary media clip in some embodiments is a mediaclip that is selected through a selection area, as shown in FIG. 34. Insome embodiments, the primary media clip is automatically selected by amedia editing application when a user invokes an automatic previewingfeature, such as those shown in FIGS. 35 and 36. As mentioned above, amedia clip of some embodiments can be video clips, audio clips, audioand video clips, sequences of media clips, effect clips, etc. When theidentified media clip is a sequence of more than one media clip, theprocess identifies the multiple media clips in the sequence.

The process 3800 then determines (at 3815) whether to preview a pre-rolland/or post-roll media clip portion. As described above, someembodiments preview media clips without a pre-roll or a post-roll whilesome embodiments preview media clips with such features in order toallow the user to view the transitions before and after the primarymedia clip. When the process determines to include the pre-roll andpost-roll clip portions in the preview, the process 3800 identifies (at3820) a portion of the pre-roll and/or post-roll media clip to display.As previously mentioned, some embodiments use a defined amount of time(e.g., 10 seconds, 20 seconds, 30 seconds, etc.) for the portion of thepre-roll and/or post-roll. For the pre-roll media clip portion, theprocess uses the out point of the preceding media clip and the definedamount of time to identify a portion of a source media file to play asthe pre-roll. For the post-roll portion, the process uses the in pointof the following media clip and the defined amount of time to identify aportion of a source media file to play as the post-roll.

Next, the process 3800 displays (at 3825) a next media clip portion. Themedia clip portion may be a pre-roll portion, a primary media clip, or apost-roll portion. When a pre-roll is used, the process first displaysthe pre-roll clip portion. Otherwise, the process displays the firstprimary media clip. As noted above, when the media clip is a sequence,there may be multiple primary media clips that are subsequentlydisplayed.

As shown in FIGS. 34-37, some embodiments display the clip portion in aselection area and/or separate preview display area of a GUI in someembodiments. To display a media clip, the process 3800 of someembodiments accesses the media clip's data structure to identify in andout points in a source file and retrieves video images from the mediaclip's source file based on the in and out points.

The process 3800 then determines (at 3830) whether any more media clipportions remain for display. When more media clips remain, the process3800 returns to 3825 to display the next media clip portion. Asdiscussed, the process may cycle through 3825 multiple times to displaythe pre-roll clip portion, one or more primary media clips, and thepost-roll clip portion. Once the process displays all of the mediaclips, the process 3800 ends.

As described above, some embodiments preview each media clip in anaudition set, either with or without the pre-roll and post-roll. In sucha situation, some embodiments perform process 3800 for each of the mediaclips in the audition set.

Many of the examples illustrated above in this section describedifferent techniques (e.g., skimming, previewing, previewing withpre-roll and/or post-roll, etc.) that allow a user to examine and/orevaluate media clips in an audition set. In some embodiments, when theuser has decided which of the media clips in the audition set the userwould like to use at the location of the audition set in the compositepresentation, the user can manually remove (e.g., using in any of themethods described above by reference to FIGS. 16 and 17) all the othermedia clips in the audition set except the media clip that the userwishes to use in the composite presentation. When the audition set onlycontains the desired media clip, the user can delete the audition setand the desired media clip replaces the audition set at the location ofthe audition set in the composite presentation. In addition, someembodiments allow the user to automatically delete the audition set, asdescribed in detail below.

D. State Diagram for GUI with Selection Area

The examples discussed above in this section describe various userinteractions with a GUI of a media editing application of someembodiments. FIG. 39 conceptually illustrates a state diagram 3900 thatshows various states and transitions between those states for the GUI100 of a media editing application of some embodiments. Specifically,FIG. 39 illustrates various states and transitions for the GUI 100 ofsome embodiments for user interaction with a selection area thatdisplays an audition set. One of ordinary skill in the art willrecognize that the various actions represented by states and transitionsof FIG. 39 are only a subset of the possible actions that can beperformed in the GUI 100 of some embodiments.

As shown in this figure, the media editing application displays the GUI100 without a selection area (at 3905). The last stage 620 shown in FIG.6 illustrates an example of the display of a GUI of some embodiments inthis state.

As shown in the stage 620 of FIG. 6, the GUI may display an audition setin the composite display area without displaying a selection area. Atthis stage, the GUI only displays the graphical representation of theactive pick in the composite display area. However, the user may wish toview the media clips in the audition set. In such cases, the userselects the user selectable audition set UI item (e.g., item 190) toinvoke the display of the selection area. When the user performs theselection, the GUI transitions to state 3915 to display the media clipsin the audition set within the selection area. With the GUI in the state3915, the user can close the selection area by selecting the auditionset UI item (e.g., by using a click control, such as a cursor clickcontrol or a touch click control, a hotkey, a keystroke, a series ofkeystrokes, a combination of keystrokes, an option selected from apop-up or pull-down menu, etc.), at which point the GUI 100 transitionsback to the state 3905 and no longer displays the selection area.

At the state 3915, the GUI displays the selection area. One example ofsuch a GUI state is the GUI 100 at the fourth stage 120 of FIG. 1. Inthis stage, the selection area 192 displays the media clips 165-175,which are the candidate media clips for inclusion at a particularlocation in a composite display area.

When the GUI is in the state 3915, the user can scroll through the mediaclips that are displayed in the selection area. The user may use scrollarrows displayed in the selection area (e.g., by clicking a cursorcontroller with the cursor over the scroll arrow, by touching the scrollarrow, etc.) or may use other scroll input (e.g., swipes on atouchscreen or touchpad, using a scroll wheel on a mouse, a hotkey orseries of keystrokes, etc.). When the user provides such scroll input,the GUI transition to state 3930

At the state 3930, the GUI of some embodiments modifies the layout ofthe media clips displayed in the selection area based on the scrollinput. For instance, when the user provides a scroll-left input, the GUIscrolls through the media clips displayed in the selection area to theleft a particular amount. Similarly, when the user provides ascroll-right input, the GUI scrolls the media clips displayed in theselection area to the right a particular amount. Stages 3110-3120 ofFIG. 31 illustrate an example of scrolling through media clips in theselection area. As illustrated here, some embodiments animate thescrolling between media clips. When the user has stopped entering scrollinput, the GUI 100 transitions back to the state 3915.

Through the selection area that the GUI of some embodiments displays inthe state 3915, the user can select a new active pick of the auditionset displayed in the selection area (e.g., by using a click operationwith a cursor controller, touchscreen, etc., by using keyboard inputsuch as a hotkey, keystroke, series of keystrokes, combination ofkeystrokes, etc., by selecting an option from a pop-up or pull-downmenu, etc.). When the user provides such input, the GUI transitions tostate 3920. At this state, the GUI displays an indicator (e.g., theindicator 196 as shown in FIG. 1) on the newly selected active pick.With the indicator displayed in the graphical representation of the newactive pick, the GUI returns to the state 3915.

The user can also move the selection area when the GUI 100 is in thestate 3915. FIG. 30 shows one method for the user to provide input tomove the selection area 192 of some embodiments by selecting an openarea of the selection area and moving it (e.g., with a cursor, through atouchscreen, etc.). When the user provides input to move the selectionarea, the GUI transitions to state 3925. At this state, the GUI modifiesthe position of the selection area based on the input provided by theuser. When the user has stopped providing input to move the selectionarea (e.g., the user has completed a click-and-drag operation on theselection area), the GUI 100 transitions back to the state 3915.

A user may also preview one or more media clips displayed in theselection area. When the user provides input to play a media clip (e.g.,by selecting a drop-down or pop-up menu option through a cursorcontroller or touchscreen, by typing a hotkey or set of keystrokes,etc.), the GUI 100 transitions to state 3910. The stages 3420-3430illustrated in FIG. 34 show one example of previewing a media clip inthe selection area of some embodiments. Some embodiments perform process3800 at state 3910 in order to play a media clip.

One of ordinary skill will recognize that the examples shown in thepreceding section are merely one illustration of how the media editingapplication of some embodiments displays the media clips of an auditionset in a selection area. For instance, other information could bedisplayed along with the media clips, such as media clips names, mediaclip durations, etc.

In addition, the transitions between states of the GUI 100 need not belimited to those shown in FIG. 39. For instance, some embodimentsinclude a transition from the state 3920 to the state 3905 when a userselects a new active pick. In other words, selecting a new active pickthrough the selection area of some embodiments causes the selection areato close (i.e., the GUI 100 no longer displays the selection area).Furthermore, as shown above, some embodiments allow the user to skimthrough a media clip at a different state of the GUI.

III. Editing an Audition Set

The media editing application of some embodiments provides users withthe ability to perform a variety of edit operations in order to create acomposite media presentation. Examples of such edit operations includetrim operations (e.g., ripple, roll, slip, and slide operations), moveoperations, add and delete operations, etc. as well as keywordoperations, marker operations, and other operations that simplify theediting process without actually modifying the composite presentation.In some embodiments, these operations may not only be performed onindividual media clips but also applied to audition sets.

A. Operations to Edit an Audition Set

One type of edit for media clips involves moving a media clip within thecomposite display area. As with a media clip, users can also move anaudition set within the composite display area in some embodiments. Asdescribed above, some embodiments treat the active pick of an auditionset as part of the composite presentation. In some such embodiments,when a user moves an audition set within the composite display area, themedia editing application moves the active pick of the audition setwithin the composite presentation.

The following FIGS. 40-42 illustrate various examples of a user movingan audition set within the composite display area 135 in order to modifya composite presentation to which the active pick of the audition setbelongs. FIG. 40 illustrates an example of the movement of an auditionset within the central compositing lane 155 of the composite displayarea 135. In particular, FIG. 40 illustrates the GUI 100 at fourdifferent stages 4005-4020 in which a user moves the audition set 185from a first location to a second location in the timeline of thecomposite presentation.

At the first stage 4005, the GUI 100 displays the audition set 185 at aparticular location in the composite display area 135 after a media clipC in the central compositing lane 155. The creation of audition set 185was illustrated in FIG. 1. At this stage, the user selects the auditionset 185 through a click operation using the cursor 160. The GUI 100indicates this selection by bolding the border of the representation ofaudition set 185 in the composite display area.

The second stage 4010 illustrates the user moving the audition set 185through a click-and-drag operation using the cursor 160 from itslocation after media clip C to a new location in the central compositinglane 155 between media clip A and media clip C. In various embodiments,the user may perform such a movement with a cursor controller, through atouchscreen, or using other input devices.

In the third stage 4015, the GUI 100 shows the media clip C moving tothe right in order to create space for the audition set 185 in thecentral compositing lane 155 as the user places the audition set 185between the media clips A and C. Some embodiments provide a feature thatautomatically moves abutting media clips in anticipation of a particularmedia clip being dropped between the abutting media clips. For instance,some such embodiments automatically move such clips when a particularmedia clip (or audition set) being moved by a user is within a thresholddistance of an edge at which two media clips in the central compositinglane are abutting (i.e., an edit point within the central compositinglane). When the particular media clip is within the threshold distanceof an edit point, the media editing application automatically moves theabutting media clips horizontally apart in order to create space for theuser to place the particular media clip in the central compositing lane155 at that location. The third stage 4015 illustrates an example ofthis automatic feature as an arrow indicates the automatic movement ofthe media clip C to the right to create space for the audition set 185in the central compositing lane 155.

The fourth stage 4020 illustrates the GUI 100 after completion of themovement of the audition set 185 within the central compositing lane155. As shown, the audition set 185 is now located between the mediaclips A and C in the composite display area 135. In terms of thecomposite presentation, the active pick of the audition set 185 is nowchronologically after the media clip A and before the media clip C.While the media clip A remains in the same location as before the move,media clip C has been moved to a later time in the compositepresentation. Some embodiments modify project data that defines thecomposite presentation to reflect this change as well as the change inmedia clip D's (the active pick of audition set 155) location in thetimeline.

FIG. 40 illustrated a movement within the central compositing lane ofthe composite display area. Some embodiments allow the user to movemedia clips and/or audition sets freely between the central compositinglane and an anchor lane, between locations in the anchor lanes, etc.FIG. 41 illustrates an example of the movement of an audition set fromthe central compositing lane 155 to an anchor lane in the compositedisplay area 135. This figure illustrates the GUI 100 at three differentstages 4105-4115 that show the user moving the audition set 185 andanchoring the audition set to a media clip.

In this example, the first stage 4105 continues from the last stage 4020of FIG. 40, as shown by the arrangement of the media clips in thecomposite display area 135 with audition set 185 between media clip Aand media clip C in the central compositing lane 155. At this stage, theuser selects the audition set 185 through a click operation using thecursor 160, as indicated by the bolding of the border of therepresentation of audition set 185.

The second stage 4110 shows the user moving the audition set 185 througha click-and-drag operation using the cursor 160 from its locationbetween media clip A and media clip C to a new location in an anchorlane above clip A. In various embodiments, the user may perform such amovement with a cursor controller, through a touchscreen, or using otherinput devices. As mentioned above, some embodiments automatically movetwo abutting media clips apart when a user places a media clip inbetween the two abutting media clips. Similarly, some embodimentsprovide a feature that automatically moves two media clips together whena user removes another media clip located between the two media clips.Some such embodiments determine when a user has moved a particular mediaclip a threshold distance from its prior location in the centralcompositing lane 155. When the user moves the particular media clipbeyond the threshold distance, the media editing applicationautomatically moves the media clips abutting each side of the particularmedia clip together to fill the open space in the central compositinglane 155. The second stage 4110 illustrates this feature as an arrowindicates the automatic movement of the media clip C to the left to fillthe open space left by the audition set 185.

The third stage 4115 illustrates the GUI 100 after completion of themovement of the audition set 185 from the central compositing lane 155to an anchor lane in the composite display area 135. As shown, theaudition set 185 is now anchored to the media clip A in an anchor laneof the composite display area 135. As described above, some embodimentsanchor a particular media clip (or audition set) onto another media clip(or audition set) when the user moves the particular media clip within athreshold distance of the other media clip. In the compositepresentation, the active pick of the audition set 185 (media clip D) isnow positioned concurrently with a portion of the media clip A and themedia clip C follows the media clip A. Some embodiments modify projectdata that defines to reflect the changes in the position of media clipsC and D.

FIG. 42, on the other hand, illustrates an example of the movement of anaudition set from a position in an anchor lane to a position in thecentral compositing lane of the composite display area. This figureillustrates the GUI 100 at three different stages 4205-4215 that showthe user moving the audition set 185 from its position anchored to mediaclip A into a position in the central compositing lane 155.

In this example, the first stage 4205 continues from the last stage 4105of FIG. 41, as shown by the arrangement of the media clips in thecomposite display area 135 with the audition set 185 anchored to mediaclip A. As shown in this stage of the GUI 100, the user selects theaudition set 185 through a click operation using the cursor 160, asindicted by the bolding of the border of the audition set 185.

The second stage 4210 shows the user moving the audition set 185 througha click-and-drag operation using the cursor 160 from its locationanchored to media clip A to a new location in the central compositinglane 155 between media clip A and media clip C. In various embodiments,the user may perform such a movement with a cursor controller, through atouchscreen, or using other input devices. As described above byreference to FIG. 40, some embodiments provide a feature thatautomatically moves abutting media clips in anticipation of a particularmedia clip being dropped between the abutting media clips. For instance,some such embodiments automatically move such clips when a particularmedia clip (or audition set) being moved by a user is within a thresholddistance of an edge at which two media clips (or audition sets) in thecentral compositing lane are abutting (i.e., an edit point within thecentral compositing lane). When the particular media clip is within thethreshold distance of an edit point, the media editing applicationautomatically moves the abutting media clips horizontally apart in orderto create space for the user to place the particular media clip in thecentral compositing lane 155 at that location. The second stage 4210illustrates an example of this automatic feature as an arrow indicatesthe automatic movement of the media clip C to the right to create spacefor the audition set 185 in the central compositing lane 155.

The third stage 4215 illustrates the GUI 100 after completion of themovement of the audition set 185 from the anchor lane to the centralcompositing lane 155 in the composite display area 135. As shown, theaudition set is no longer anchored to media clip A and instead sitsbetween media clip A and media clip C in the central compositing lane155. While the media clip A remains in the same location as before themove, media clip C has been moved to a later time in the compositepresentation. Some embodiments modify project data that defines thecomposite presentation to reflect this change as well as the change inmedia clip D's (the active pick of audition set 155) location in thetimeline.

The several examples discussed above describe moving an audition set toand from various positions in a composite display area of someembodiments by dragging the audition set within the composite displayarea. Other embodiments provide other ways to move the audition set. Forinstance, some such embodiments provide a cut and paste operation formoving the audition set to different places in the composite displayarea. Moreover, instead of moving an audition set within the compositedisplay area, some embodiments allow a copy (e.g., duplicate) of theaudition set to be made and placed in the composite display area.

Another edit operation that can be performed on an audition set in someembodiments is a split edit operation (also referred to as a cut editoperation, razor blading, blading, etc.). FIG. 43 illustrates a splitedit operation performed on an audition set using the GUI 100 accordingto some embodiments of the invention. Specifically, this figureillustrates the GUI 100 at six different stages 4305-4330 that show asplit edit operation of some embodiments performed on an audition set.

The GUI 100 in this figure continues from the last stage 620 illustratedin FIG. 6, at which point an audition set 630 is created. For purposesof clarity and explanation, the horizontal display length of theaudition set 630 is displayed differently in the composite display area135 for this example. At the first stage 4305, the GUI 100 displays amenu 4335 that includes a user selectable “Split” option along withother user selectable options (not shown). The “Split” option invokes anedit tool of some embodiments for performing a split edit operation. Insome embodiments, the user invokes the menu 4335 by performing a clickoperation (e.g., a cursor click or a touch click). Other embodimentsprovide other ways to invoke the menu 4335. For example, some of theseembodiments allow the user to invoke the menu 4335 using a hotkey, akeystroke, a series of keystrokes, a combination of keystrokes, anoption from a pop-up or pull-down menu, or any other appropriate methodto invoke a menu. The first stage 4305 also shows the user selecting the“Split” option through a click operation using the cursor 160.

In the second stage 4310, the GUI 100 displays a splitting tool 4340. Insome embodiments, the GUI 100 displays the splitting tool 4340 in placeof the cursor 160 when the user selects the “Split” option in the menu4335. In this example, the user invokes the split edit operation on anaudition set in the composite display area 135 by performing a clickoperation (e.g., a cursor click or a touch click) on the audition setusing the splitting tool 4340.

At third stage 4315 of the GUI 100, the user invokes the split editoperation on the audition set 630 through a click operation using thesplitting tool 4335. As shown in this stage, the split edit operation isinvoked at the point in the audition set 630 indicated by the splittingtool 4335.

The fourth stage 4320 shows the GUI 100 after the completion of thesplit edit operation on the audition set 630. As illustrated in thisstage, the GUI 100 no longer displays the audition set 630 in thecomposite display area 135. Instead, the GUI 100 displays audition sets4345 and 4350 in its place. This is indicated by the audition sets 4345and 4350 each displaying the user selectable UI item 190. As shown, theGUI 100 no longer displays the splitting tool 4340 and displays thecursor 160 in its place. In some embodiments, the GUI 100 automaticallydisplays the cursor 160 in place of the splitting tool 4340 uponcompletion of split edit operation (e.g., after the user has performed aclick operation on the audition set 630).

In this example, when the user invokes the split edit operation on theaudition set 630, the media editing application splits the active pickof the audition set 630 (the media clip 175 in this example) at thepoint indicated by the splitting tool 4340 into two media clip 4355 and4360 and creates the audition sets 4345 and 4350. Each of the auditionsets 4345 and 4350 includes all the media clips in the audition set 630except the active pick of the audition set 630 when the split editoperation was performed on the audition set 630 (the media clip 175 inthis example). Each of the audition sets 4345 and 4350 includes one ofthe split media clips 4355 and 4360, which is set as the active pick ofits respective audition set. In this example, the audition set 4345includes the media clip 4355, which is set as its active pick.Similarly, the audition set 4350 includes the media clip 4360, which isset as its active pick. In some embodiments, when the split editoperation is invoked, the media editing application creates the datastructures for the media clips 4345 and 4350 with in and out points thatcorrespond to the point of the split edit operation. The media editingapplication also creates data structures for the audition sets 4345 and4350 in some such embodiments.

The fifth and sixth stages 4325 and 4330 each illustrate the GUI 100displaying the selection area 192 of each of the audition sets 4345 and4350. The user invokes the selection area 192 for each audition set 4345and 4350 by selecting the corresponding audition set's UI item 190through a click operation (e.g., a cursor click or a touch click) orusing any of the methods previously mentioned above. As shown in thefifth stage 4325, the selection area 192 for the audition set 4345displays the media clips 4355 and 165, which are the media clipsincluded in the audition set 4345. Similarly, at the sixth stage 4330 ofthe GUI 100, the selection area 192 for the audition set 4350 displaysthe media clips 4360 and 165, which are the media clips included in theaudition set 4350.

While FIG. 43 illustrates a split edit operation using the splittingtool 4340, in some embodiments, the GUI 100 does not display thesplitting tool 4340 when the “Split” option is selected. Rather, the GUI100 continues to display the cursor 160 and the user can perform thesplit edit operation on the audition set 630 in a similar fashionillustrated in FIG. 43. Furthermore, FIG. 43 shows the split editoperation invoked through a selection of a pop-up menu. Some embodimentsallow the split edit operation to be invoked in different ways, such asusing a hotkey, a keystroke, a series of keystrokes, a combination ofkeystrokes, a selection through a pull-down menu, or any other method ofinvoking a edit operation.

Several of the above examples (e.g., FIGS. 8 and 12) describe applyingan effect to one media clip in the audition set. However, someembodiments of the media editing application allow the user to add aparticular effect to all the media clips of an audition set.

FIG. 44 illustrates applying an effect to the media clips of an auditionset using the GUI 800 according to some embodiments of the invention.This figure illustrates the GUI 800 at six different stages 4405-4430that show an effect applied to all the media clips of the audition set185.

As shown in the first stage 4405, the composite display area 135displays the audition set 185, which is created in a similar fashion asdescribed above by reference to FIG. 1. Similar to FIG. 8, the “Video”tab was selected in this example to display the video effects items830-840 in the effects panel 825, as shown in this stage. The firststage 4405 also illustrates the user selecting the effect item 830 anddragging it onto the audition set 185 (e.g., through a drag-and-dropoperation) in a similar fashion illustrated in FIG. 8. In someembodiments of the media editing application, the GUI 4405 displays amenu 4435 when the user has finished dragging the effect item 830 ontothe audition set 185 (e.g., the user performs the drop portion of adrag-and-drop operation).

The second stage 4410 shows the GUI 4410 displaying a menu 4435 thatincludes a user selectable “Add Effect to All” option and other userselectable options (not shown) as well. The “Add Effect to All” optionapplies one or more effects associated with a selected effect item(“blur” for the effect item 830 in this example) to all the media clipsin a selected audition set (the audition set 185 in this example) whenthe option is selected. This stage also shows the user selecting the“Add Effect to All” option through a click operation using the cursor160.

In the third stage 4415, the media editing application has applied theeffect associated with the effect item 830 (“blur”) to all the mediaclips in the audition set 185. This stage also shows the user selectingthe user selectable UI item 190 through a click operation using thecursor 160 in order to invoke the display of the selection area 192.

The fourth stage 4420 of the GUI 800 displays the selection area 192. Asshown, the selection area 192 displays media clips 165-175. As mentionedabove, some embodiments display a label above a media clip in theselection area 192. In some of these embodiments, the label for a mediaclip that has an effect applied to it is specified with the name of theeffect appended to the name of the media clip. As such, the labels forthe respective media clips displayed in the fourth through sixth stages4420-4430 specify such names. Specifically, the label for the media clip175 displayed in the fourth stage 4420 is “Clip D—Blur,” the label forthe media clip 165 displayed in fifth stage 4425 is “Clip E—Blur,” andthe label for the media clip 170 displayed in the sixth stage 4430 is“Clip F—Blur.”

Although the figure above illustrates an effect applied to all the mediaclips in an audition set, the effect does not necessarily have to beapplied to all the media clips in some embodiments. For instance, someembodiments may apply the effect to every media clip except the activepick. Some embodiment may apply the effect to only the media clips thatare versions (i.e., duplicates).

Moreover, in some embodiments, the user may be required to use inputmodifiers when performing the effect operation described above. Forexample, while selecting and dragging an effect item onto a media clip,some embodiments may require the user to press and hold a hotkey, akeystroke, a combination of keystrokes, etc. In some embodiments, theuser may be required to only press (and not hold) such input modifiers.Other embodiments may require other types of input modifiers to performthe effect operation described above. In this manner, the media editingapplication of some embodiment is able to differentiate among differenteffect operations, such as the operations described in FIG. 12 and FIG.44, that the user wishes to perform and thus present the correct optionsto the user (e.g., displaying the correct menu options).

The above figures in this section illustrate a number of different editoperations that a user can perform on an audition set. FIG. 45conceptually illustrates a process 4500 of some embodiments forperforming an edit operation to an audition set. The process 4500 startsby receiving (at 4505) input to perform an edit operation on an auditionset. The input may be received through a composite display area when auser edits the audition set displayed in the composite display area(e.g., a move edit as shown in FIGS. 40-42, a trim edit, adding anaudition set to or removing an audition set from the composite displayarea, etc.). Other inputs may involve a user dragging an effects itemonto an audition set (e.g., as shown in FIG. 44), selecting a menuoption (e.g., as shown in FIG. 43), or other editing input. Such editinginput may be received through various operations performed with a cursorcontroller, a touchscreen, etc.

Next, the process 4500 determines (at 4510) whether to apply the editoperation to all the media clips in the audition set. As describedabove, some operations (e.g., trim operations, move operations, etc.)are applied only to the active pick of an audition set. Other operations(e.g., application of an effect) may be applied to either just theactive pick or all media clips in the audition set.

When the edit is to be applied to all of the media clips in the auditionset, the process 4500 applies (at 4515) the edit operation to each mediaclip in the audition set. In some embodiments, this entails the process4500 modifying the data structure of each of the media clips and/or thedata structure of the audition set based on the edit operation. FIG. 44illustrates an example of an edit operation that is applied to each ofthe media clips in the audition set. Specifically, FIG. 44 shows aneffect applied to each of the media clips in the audition set. Asanother example, some embodiments allow a user to apply a trim editoperation to modify the in and/or out points of each media clip in a setby a particular amount of time. In such cases, the process 4500 modifiesthe in and out points of each of the media clips in the audition setbased on the trim edit operation. After the process 4500 applies theedit operation to each media clip in the audition set, the process 4500ends.

On the other hand, when the edit is not to be applied to all of themedia clips in the audition set, the process 4500 applies (at 4520) theedit operation to the active pick of the audition set. In theseinstances, the process 4500 modifies the data structure of the activepick and/or the data structure of the audition set based on the editoperation. FIGS. 40-42 show several examples of an edit operation thatis applied to only the active pick of the audition set. In thosefigures, an audition set is moved from one location in the compositedisplay area to another location in the composite display area. When theaudition set is moved to a new location in the composite display area,some embodiments modify the data structure of the active pick and/or theaudition set to reflect the audition set's new location in the compositedisplay area.

Another type of edit operation that is applied only to the active pickof an audition set is shown in FIG. 43. In that example, the mediaediting application applies a split or blade edit operation to only theactive pick of the audition set. Additional and/or different editoperations that are applied only to the active pick of an audition setare provided in some embodiments. Examples of such edit operationsinclude a trim edit, ripple edit, roll edit, etc. After the process 4500applies the edit operation to the active pick, the process 4500 ends.

B. Deleting an Audition Set

Different embodiments provide different methods for deleting or removingan audition set from a composite presentation. For instance, someembodiments allow the user to delete the audition set (e.g., using ahotkey, a keystroke, a series of keystrokes, a combination ofkeystrokes, an option selected from a pop-up or pull-down menu, or anyother appropriate method) as the user typically would a media clip inthe composite presentation. As another example, when the user isfinished evaluating the media clips in an audition set and has decidedwhich media clip in the audition set to include in the compositepresentation, some embodiments provide an operation that sets the activepick of an audition set as the committed media clip in the compositepresentation (also referred to as a “finalize” operation) and deletesthe audition set.

FIG. 46 illustrates an example of such a finalize operation. Inparticular, FIG. 46 illustrates the GUI 100 at four different stages4605-4620 that show a media clip of an audition set being committed to acomposite presentation and the deletion of the audition set.

For this example, the first stage 4605 continues from the last stage 620of FIG. 6. As shown, this stage illustrates the user selecting theaudition set 630 through a click operation using the cursor 160. Afterthe audition set 630 has been selected, the user selects the userselectable UI item 190 through a click operation using the cursor 160 toinvoke the display of the selection area 192. The user may wish todisplay the selection area 192 to check that the active pick of theaudition set the media clip that the user wishes to commit to thecomposite presentation. As mentioned above, the media editingapplication of some embodiments automatically displays the selectionarea 192 when the UI item 190 is selected.

At the second stage 4610, the GUI 100 displays the selection area 192.As shown, the media clip 165 and the media clip 175 (“Clip D”) aredisplayed in the selection area 192. In addition, the indicator 196 isdisplayed on the media clip 175 to indicate that it is the active pickof the audition set 630.

The third stage 4615 of the GUI 100 displays a menu 4625 that includes auser selectable “Finalize” option as well as other user selectableoptions (not shown). The “Finalize” option invokes the operation tocommit the active pick of the audition set 630 to the compositepresentation and delete the audition set 630. In this example, the userinvokes the menu 4625 by selecting the “Stacks” option in the menu bar150 through a click operation using the cursor 160. In some embodiments,other methods are provided for invoking the menu 4625 as well. Forinstance, some such embodiments allow the user to invoke the menu 4625using a hotkey, a keystroke, a series of keystrokes, a combination ofkeystrokes, or any other method to invoke a menu. The third stage 4615also illustrates the user selecting the “Finalize” option through aclick operation using the cursor 160.

The fourth stage 4620 illustrates the GUI 100 after the active pick ofthe audition set 630 (the media clip 175) has been committed to thecomposite presentation and the audition set 630 has been deleted. Sincethe audition set 630 has been deleted, the user selectable UI item 190is no longer displayed and the media clip 175 has replaced the auditionset 630 in the composite presentation, as illustrated in the compositedisplay area 135.

FIG. 46 describes a particular series of operations for committing theactive pick of the audition set 630 to the composite presentation anddeleting the audition set 630. However, other embodiments do notnecessarily perform all of these operations to commit the active pick tothe composite presentation and delete the audition set 630. For example,some such embodiments do not select the UI item 190 to display theselection area 192. In such cases, the user selects the audition set 630and then selects the “Finalize” option in the menu 4625 to commit theactive pick of the audition set 630 to the composite presentation anddelete the audition set 630.

Instead of performing a “finalize” operation on an audition set in acomposite presentation, the user of the media editing application maywish to commit the active picks of all the audition sets in thecomposite presentation and delete all of the audition sets. FIG. 47illustrates an example of such an operation. As shown, FIG. 47illustrates the GUI 100 at three different stages 4705-4715 that show anoperation that performs a “finalize” operation on all of the auditionsets in a composite presentation.

As shown in the first stage 4705, the composite presentation that isdisplayed in the composite display area 135 includes an audition set4720 and the audition set 185, as indicated by the display of the userselectable UI item 190 on each audition set. The audition set 4720 canbe created in the same or similar manner as many of the embodiments forcreating an audition set described above.

At the second stage, the GUI 100 displays a menu 4725 that includes auser selectable “Finalize All” option and other user selectable options(not shown). The “Finalize All” option invokes an operation that commitsto the composite presentation each of the active picks of all theaudition sets in the composite presentation and deletes all the auditionsets. Some embodiments display the menu 4725 when the user selects the“Stacks” option in the menu bar 150 (e.g., through a click operationsuch as a cursor click or a touch click). However, other embodimentsprovide other ways for the user to invoke the menu 4725. For example,some such embodiments allow the user to invoke the menu 4725 using ahotkey, a keystroke, a series of keystrokes, a combination ofkeystrokes, or any other appropriate method to invoke a menu. As shown,the second stage 4710 shows the user selecting the “Finalize All” optionthrough a click operation using the cursor 160.

The third stage 4715 illustrates the GUI 100 after the active picks ofall the audition sets in the composite presentation have been committedto the composite presentation and all the audition sets have beendeleted. As shown, the user selectable UI items 190 are no longerdisplayed, indicating that that audition sets 4720 and 185 have beendeleted. Also, Clip A has replaced the audition set 4720 and Clip D hasreplaced the audition set 185 in the composite presentation asillustrated in the composite display area 135.

The FIGS. 46 and 47 describe above show different methods for deletingaudition sets in the composite display area 135. As mentioned above,some embodiments allow the user to create audition sets in the eventlibrary 145. As such, some of these embodiments also allow the user todelete audition sets in the media library 145. The following figureillustrates one such example.

FIG. 48 illustrates deleting an audition set using the GUI 100 of someembodiments. In particular, this figure illustrates the GUI 100 at fourdifferent stages 4805-4820 that show the deletion of an audition set inthe media library 145 (also referred to as unstacking) in someembodiments.

In this example, the first stage 4805 of the GUI 100 continues from thelast stage 2630 illustrated in FIG. 26. This stage of the GUI 100 showsthe user selecting the audition set 2655 in the media library 145through a click operation using the cursor 160.

At the second stage 4810, the GUI 100 displays a menu 4825 that includesa user selectable “Unstack” option and other options (not shown). Forthis example, the “Unstack” option invokes a command to delete theaudition set 2655 and place the media clips in the audition set 2655 atindividual positions in the media library 145. In some embodiments, theuser invokes the menu 4825 by selecting the “Stacks” option in the menubar 150. Other embodiments provide other ways for the user to invoke themenu 4825. For example, some such embodiments allow the user to invokethe menu 4825 using a hotkey, a keystroke, a series of keystrokes, acombination of keystrokes, or any other appropriate method to invoke amenu. The second stage 4810 also shows the user selecting the “Unstack”option through a click operation using the cursor 160.

The third stage 4815 shows the GUI 100 after the invocation of thedelete operation. As shown, an animation is being displayed that showsthe media editing application, in response to the invocation of thedelete operation, automatically moving the media clip 2650 to an area inthe media library 145 that is not occupied by another media clip. Otheranimations that show the deletion of the audition set are possible. Someembodiments may not even display an animation (i.e., the media clip 2655will just be displayed in an empty area in the media library 145) of thedelete operation.

At the fourth stage 4820 of the GUI 100, the delete operation iscompleted. As shown, the media clips 2635 and 2650 are no longerdisplayed as media clips stacked on top of each other, but, instead, aredisplayed at individual locations in the media library 145. In addition,the user selectable UI item 2660 is not longer displayed in the mediaclip 2650. This stage also shows the media clips 2635 and 2650 stillselected, as indicated by the bolded borders of each of the media clips.In some embodiments, the media clips 2635 and 2650 do not remainselected after the completion of the delete operation.

While FIG. 48 illustrates the deletion of a single audition set in themedia library 145, some embodiments allow the user to select multipleaudition sets in the media library 145 before invoking the deleteoperation. In some of these embodiments, the media clips in the selectedaudition sets would each be moved to an area in the media library 145that is not occupied by another media clip.

The above subsection describes various techniques for deleting, orfinalizing, an audition set. FIG. 49 conceptually illustrates a process4900 for finalizing an audition set. As shown, the process begins byreceiving (at 4905) input to finalize an audition set in the compositedisplay area. In some embodiments, a user provides such input throughthe selection of an item from a menu (e.g., through a cursor controllerselection, a touchscreen selection, etc.), a hotkey or other keystrokeinput, etc.

The process removes (at 4910) any audition set indicator from thedisplay of the graphical representation of the audition set. Rather thandisplaying an audition set, the GUI 100 now displays a media cliprepresentation of the active pick of the audition set. When the auditionset is located in the media library, some embodiments unstack thedisplay of the audition set and display each of the media clips from theset separately.

The process also deletes (at 4915) the data structure for the auditionset, then ends. When the audition set data structure is defined byreferences to separate data structures for each of the media clips, thissimply involves deleting the audition set data structure. When the mediaclip information (e.g., in and out points in the source media file) isstored as part of the audition set data structure, some embodimentscreate separate data structures for each of the individual media clips.

IV. Software Architecture

In some embodiments, the processes described above are implemented assoftware running on a particular machine, such as a computer or ahandheld device, or stored in a computer readable medium. FIG. 50conceptually illustrates the software architecture of a media editingapplication 5000 of some embodiments. In some embodiments, the mediaediting application is a stand-alone application or is integrated intoanother application, while in other embodiments the application might beimplemented within an operating system. Furthermore, in someembodiments, the application is provided as part of a server-basedsolution. In some such embodiments, the application is provided via athin client. That is, the application runs on a server while a userinteracts with the application via a separate machine remote from theserver. In other such embodiments, the application is provided via athick client. That is, the application is distributed from the server tothe client machine and runs on the client machine.

As shown, the media editing application 5000 includes a user interface(UI) interaction module 5005, a selection area management module 5010, aset of editing modules 5015, a preview generator 5020, an active pickselector 5025, an audition set manager 5040, and a rendering engine5045. The media editing application 5000 also includes project data 5030and source files 5035. In some embodiments, the source files 5035 storethe media content (e.g. text, audio, image, and video content) data ofmedia clips. The project data 5030 stores data structures for sequences,media clips, audition sets, etc. that include references to mediacontent data stored as .mov, .avi, .jpg, .png, mp3, way, txt, etc. filesin the source files 5035. In some embodiments, storages 5030 and 5035are all stored in one physical storage. In other embodiments, thestorages are in separate physical storages. In some cases, for example,the source files 5035 may be stored across multiple hard drives, networkdrives, etc.

FIG. 50 also illustrates an operating system 5050 that includes inputdevice driver(s) 5055 and display module 5060. In some embodiments, asillustrated, the input device drivers 5055 and display module 5060 arepart of the operating system 5050 even when the media editingapplication is an application separate from the operating system 5050.

The input device drivers 5055 may include drivers for translatingsignals from a keyboard, mouse, touchpad, tablet, touch screen, etc. Auser interacts with one or more of these input devices, which sendsignals to their corresponding device driver. The device driver thentranslates the signals into user input data that is provided to the UIinteraction module 5005.

The present application describes a graphical user interface thatprovides users with numerous ways to perform different sets ofoperations and functionalities. In some embodiments, these operationsand functionalities are performed based on different commands that arereceived from users through different input devices (e.g., keyboard,track pad, touchpad, mouse, etc.). For example, the present applicationdescribes the use of a cursor in the graphical user interface to control(e.g., select, move) objects in the graphical user interface. However,in some embodiments, objects in the graphical user interface can also becontrolled or manipulated through other controls, such as touch control.In some embodiments, touch control is implemented through an inputdevice that can detect the presence and location of touch on a displayof the device. An example of such a device is a touch-screen device. Insome embodiments, with touch control, a user can directly manipulateobjects by interacting with the graphical user interface that isdisplayed on the display of the touch-screen device. For instance, auser can select a particular object in the graphical user interface bysimply touching that particular object on the display of thetouch-screen device. As such, when touch control is utilized, a cursormay not even be provided for enabling selection of an object of agraphical user interface in some embodiments. However, when a cursor isprovided in a graphical user interface, touch control can be used tocontrol the cursor in some embodiments.

The display module 5060 translates the output of a user interface for adisplay device. That is, the display module 5060 receives signals (e.g.,from the UI interaction module 5005) describing what should be displayedand translates these signals into pixel information that is sent to thedisplay device. The display device may be an LCD, plasma screen, CRTmonitor, touch screen, etc.

The UI interaction module 5005 of the media editing application 5000interprets the user input data received from the input device drivers5055 and passes it to various modules, including the selection areamanagement module 5010, the audition set manager 5040, the editingmodules 5015, and the preview generator 5020. The UI interaction modulealso manages the display of the UI and outputs this display informationto the display module 5060. This UI display information may be based oninformation from the selection area management module 5010, the auditionset manage 5040, etc., or directly from input data (e.g., when a usermoves an item in the UI that does not affect any of the other modules ofthe media editing application 5000).

The audition set manager 5040 receives the various audition set commands(e.g., to create an audition set, add a media clip to an audition set,remove a media clip from audition set, delete an audition set, etc.) andcreates and/or modifies the data structures for the audition sets. Theaudition set manager 5040 stores this audition set information in theproject data 5030 in some embodiments. In addition, the audition setmanager 5040 receives audition set editing commands (e.g., split, trim,etc.) and determines which of the media clips in the audition set shouldbe edited by the editing modules 5015.

The active pick selector 5025 chooses an active pick from a set of clipsin an audition set. The active pick selector is used by the audition setmanager 5040 anytime the audition set manager needs to choose an activepick for an audition set (e.g., when creating a new audition set, addinga clip to an audition set, or deleting the current active pick of anaudition set). The active pick selector chooses the active pick,enabling the audition set manager 5040 to modify the data structure forthe audition set to identify the active pick.

The selection area management module 5010 manages the display of theselection area of some embodiments. The selection area management module5010 generates the selection area using information in the datastructure for an audition set stored in the project data 5030 and passesthis display information to the UI interaction module 5005 forincorporation into the user interface. The selection area managementmodule 5010 also receives user input from the UI interaction module 5005to modify the selection area (e.g., scroll through media clips, skimthrough a media clip, preview a media clip, move the selection area,resize the selection area, etc.).

The editing modules 5015 receive the various editing commands (trimming,splitting, and applying effect to media clips, audition sets, andsequences, creating sequences, etc.) and create and modify the projectdata 5030 describing the affected media clips, audition sets, andsequences in the composite display area and/or media library.

The preview generator 5020 enables the output of audio and video fromthe media editing application so that a user can preview clips orcomposite sequences. The preview generator 5020 uses the project dataand the source media to send display instructions to the UI interactionmodule 5005, which incorporates the preview into the user interface.

The rendering engine 5045 enables the storage or output of a compositemedia presentation using the media editing application 5000. Therendering engine 5045 receives data from the editing modules 5015 and/orstorages 5030 and 5035 and, in some embodiments creates a compositemedia presentation from the source files 5035. The composite mediapresentation can be stored in one of the illustrated storages or adifferent storage.

While many of the features have been described as being performed by onemodule (e.g., the audition set manager 5040 or the preview generator5020), one of ordinary skill would recognize that the functions might besplit up into multiple modules. Similarly, the functions described asbeing performed by multiple different modules might be performed by asingle module in some embodiments (e.g., the active pick selector 5025might be part of the audition set manager 5040.

V. Computer System

Many of the above-described features and applications are implemented assoftware processes that are specified as a set of instructions recordedon a computer readable storage medium (also referred to as computerreadable medium). When these instructions are executed by one or moreprocessing unit(s) (e.g., one or more processors, cores of processors,or other processing units), they cause the processing unit(s) to performthe actions indicated in the instructions. Examples of computer readablemedia include, but are not limited to, CD-ROMs, flash drives, RAM chips,hard drives, EPROMs, etc. The computer readable media does not includecarrier waves and electronic signals passing wirelessly or over wiredconnections.

In this specification, the term “software” is meant to include firmwareresiding in read-only memory or applications stored in magnetic storagewhich can be read into memory for processing by a processor. Also, insome embodiments, multiple software inventions can be implemented assub-parts of a larger program while remaining distinct softwareinventions. In some embodiments, multiple software inventions can alsobe implemented as separate programs. Finally, any combination ofseparate programs that together implement a software invention describedhere is within the scope of the invention. In some embodiments, thesoftware programs, when installed to operate on one or more electronicsystems, define one or more specific machine implementations thatexecute and perform the operations of the software programs.

FIG. 51 conceptually illustrates an electronic system 5100 with whichsome embodiments of the invention are implemented. The electronic system5100 may be a computer, phone, PDA, or any other sort of electronicdevice. Such an electronic system includes various types of computerreadable media and interfaces for various other types of computerreadable media. Electronic system 5100 includes a bus 5105, processingunit(s) 5110, a graphics processing unit (GPU) 5120, a system memory5125, a read-only memory 5130, a permanent storage device 5135, inputdevices 5140, and output devices 5145.

The bus 5105 collectively represents all system, peripheral, and chipsetbuses that communicatively connect the numerous internal devices of theelectronic system 5100. For instance, the bus 5105 communicativelyconnects the processing unit(s) 5110 with the read-only memory 5130, theGPU 5120, the system memory 5125, and the permanent storage device 5135.

From these various memory units, the processing unit(s) 5110 retrieveinstructions to execute and data to process in order to execute theprocesses of the invention. The processing unit(s) may be a singleprocessor or a multi-core processor in different embodiments. Someinstructions are passed to and executed by the GPU 5120. The GPU 5120can offload various computations or complement the image processingprovided by the processing unit(s) 5110. In some embodiments, suchfunctionality can be provided using CoreImage's kernel shading language.

The read-only-memory (ROM) 5130 stores static data and instructions thatare needed by the processing unit(s) 5110 and other modules of theelectronic system. The permanent storage device 5135, on the other hand,is a read-and-write memory device. This device is a non-volatile memoryunit that stores instructions and data even when the electronic system5100 is off. Some embodiments of the invention use a mass-storage device(such as a magnetic or optical disk and its corresponding disk drive) asthe permanent storage device 5135.

Other embodiments use a removable storage device (such as a floppy disk,flash drive, or ZIP® disk, and its corresponding disk drive) as thepermanent storage device. Like the permanent storage device 5135, thesystem memory 5125 is a read-and-write memory device. However, unlikestorage device 5135, the system memory is a volatile read-and-writememory, such a random access memory. The system memory stores some ofthe instructions and data that the processor needs at runtime. In someembodiments, the invention's processes are stored in the system memory5125, the permanent storage device 5135, and/or the read-only memory5130. For example, the various memory units include instructions forprocessing multimedia clips in accordance with some embodiments. Fromthese various memory units, the processing unit(s) 5110 retrieveinstructions to execute and data to process in order to execute theprocesses of some embodiments.

The bus 5105 also connects to the input and output devices 5140 and5145. The input devices enable the user to communicate information andselect commands to the electronic system. The input devices 5140 includealphanumeric keyboards and pointing devices (also called “cursor controldevices”). The output devices 5145 display images generated by theelectronic system. The output devices include printers and displaydevices, such as cathode ray tubes (CRT) or liquid crystal displays(LCD). Some embodiments include devices such as a touchscreen thatfunction as both input and output devices.

Finally, as shown in FIG. 51, bus 5105 also couples electronic system5100 to a network 5165 through a network adapter (not shown). In thismanner, the computer can be a part of a network of computers (such as alocal area network (“LAN”), a wide area network (“WAN”), or an Intranet,or a network of networks, such as the Internet. Any or all components ofelectronic system 5100 may be used in conjunction with the invention.

Some embodiments include electronic components, such as microprocessors,storage and memory that store computer program instructions in amachine-readable or computer-readable medium (alternatively referred toas computer-readable storage media, machine-readable media, ormachine-readable storage media). Some examples of such computer-readablemedia include RAM, ROM, read-only compact discs (CD-ROM), recordablecompact discs (CD-R), rewritable compact discs (CD-RW), read-onlydigital versatile discs (e.g., DVD-ROM, dual-layer DVD-ROM), a varietyof recordable/rewritable DVDs (e.g., DVD-RAM, DVD-RW, DVD+RW, etc.),flash memory (e.g., SD cards, mini-SD cards, micro-SD cards, etc.),magnetic and/or solid state hard drives, read-only and recordableBlu-Ray® discs, ultra density optical discs, any other optical ormagnetic media, and floppy disks. The computer-readable media may storea computer program that is executable by at least one processing unitand includes sets of instructions for performing various operations.Examples of computer programs or computer code include machine code,such as is produced by a compiler, and files including higher-level codethat are executed by a computer, an electronic component, or amicroprocessor using an interpreter.

While the above discussion primarily refers to microprocessor ormulti-core processors that execute software, some embodiments areperformed by one or more integrated circuits, such as applicationspecific integrated circuits (ASICs) or field programmable gate arrays(FPGAs). In some embodiments, such integrated circuits executeinstructions that are stored on the circuit itself.

As used in this specification and any claims of this application, theterms “computer”, “server”, “processor”, and “memory” all refer toelectronic or other technological devices. These terms exclude people orgroups of people. For the purposes of the specification, the termsdisplay or displaying means displaying on an electronic device. As usedin this specification and any claims of this application, the terms“computer readable medium,” “computer readable media,” and “machinereadable medium” are entirely restricted to tangible, physical objectsthat store information in a form that is readable by a computer. Theseterms exclude any wireless signals, wired download signals, and anyother ephemeral signals.

While the invention has been described with reference to numerousspecific details, one of ordinary skill in the art will recognize thatthe invention can be embodied in other specific forms without departingfrom the spirit of the invention. In addition, a number of the figures(including FIGS. 9, 15, 18, 38, 45, and 49) conceptually illustrateprocesses. The specific operations of these processes may not beperformed in the exact order shown and described. The specificoperations may not be performed in one continuous series of operations,and different specific operations may be performed in differentembodiments. Furthermore, the process could be implemented using severalsub-processes, or as part of a larger macro process.
